The value of x in the lines is 126 degree

We are given that;

Three parallel line and one intersecting line

Angles= (x-6) and 60

Now,

By supplementary angles property

Angle 1 + Angle 2 = 180 degree

Substituting the values of angles

x-6 + 60 = 180

x + 54 = 180

x = 180-54

The required sine function is

y = 2 sin (3π/4 (x) + 3

For given function,

A sine function that has a midline of 3, an amplitude of 2 and a period of 3pi/4

A = 2

T = 3π/4

Since we know

The values of all trigonometric functions depending on the ratio of sides in a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.

In this case, the midline is 3

⇒ D = 3

Using the generalized equation of sine function,

y = A sin (B (x + C)) + D

y = 2 sin (3π/4 (x + 0) + 3

y = 2 sin (3π/4 (x) + 3

Therefore, the required sine function is

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

Length of rectangle = 4 cm

Width of rectangle = 7 cm

Since, WE know that;

Area of rectangle = Lenght x Width

Hence, We get;

Area of rectangle = 4 x 7

Area of rectangle = 28 cm²

Your ability to borrow money at lower rates improves as your credit score increases. Option D.

Your ability to borrow money at lower rates improves as your credit score increases.

A higher credit score indicates to lenders that you have a strong credit history, responsible financial behavior, and a lower risk of defaulting on loans.

Lenders view borrowers with higher credit scores as more reliable and trustworthy, making them more likely to offer lower interest rates and better loan terms.

While saving more and earning more can indirectly contribute to improving your credit score by positively impacting your financial stability and ability to manage debt, they are not direct factors that lenders consider when determining interest rates.

Answer: To prove the given identity:

(cosec A - sec A)(cot A - tan A) = (cosec A + sec A)(sec A cosec A - 2)

We will start by simplifying both sides of the equation.

Left-hand side (LHS):

(cosec A - sec A)(cot A - tan A)

Using trigonometric identities, we can rewrite cosec A, sec A, cot A, and tan A in terms of sin A and cos A:

Substituting these values into the LHS:

(cosec A - sec A)(cot A - tan A)

= (1/sin A - 1/cos A)(cos A / sin A - sin A / cos A)

= ((cos A - sin A) / (sin A * cos A)) * ((cos A^2 - sin A^2) / (sin A * cos A))

= (cos^2 A - sin^2 A) / (sin^2 A * cos^2 A) [Using the difference of squares identity: a^2 - b^2 = (a + b)(a - b)]

= ((cos A + sin A)(cos A - sin A)) / (sin^2 A * cos^2 A)

Right-hand side (RHS):

(cosec A + sec A)(sec A cosec A - 2)

Again, using the same trigonometric identities:

Now, we need to show that the LHS is equal to the RHS:

((cos A + sin A)(cos A - sin A)) / (sin^2 A * cos^2 A) = (cos A + sin A) / (sin^2 A * cos^2 A) * (1 - 2sin^2 A * cos^2 A)

To prove this, we can cancel out the common factors in the numerator and denominator of the LHS:

(cos A - sin A) = 1 - 2sin^2 A * cos^2 A

Next, we'll simplify both sides individually:

Therefore, the LHS is equal to the RHS, and the given identity has been proven.

The solution is: the dimensions of the flag in inches is:

40 inches by 55 inches.

The flag is rectangular in nature and the formula for calculating the perimeter of a rectangle is P = 2(L+W) where;

L is the length of the flag

W is the width of the flag

From the diagram, L = y and W = 11y/8

Since the perimeter = 190 inches, we will substitute the given parameters into the formula and firs calculate the value of y.

190 = 2(y+11y/8)

190 = 2y + 11y/4

multiply through by 4

760 = 8y+11y

760 = 19y

y = 760/19

y = 40

The length of the flag is 40 inches and the Width of the flag is 11(40)/8 = 55inches.

Hence, the dimensions of the flag in inches is 40 inches by 55 inches.

Answer:

Step-by-step explanation:

The three equivalent equations are 2 + x = 5, x + 1 = 4 and -5 + x = -2. So, correct options are A, B and E.

Two equations are considered equivalent if they have the same solution set. In other words, if we solve both equations, we should get the same value for the variable.

To determine which of the given equations are equivalent, we need to solve them for x and see if they have the same solution.

Let's start with the first equation:

2 + x = 5

Subtract 2 from both sides:

x = 3

Now let's move on to the second equation:

x + 1 = 4

Subtract 1 from both sides:

x = 3

Notice that we got the same value of x for both equations, so they are equivalent.

Next, let's look at the third equation:

9 + x = 6

Subtract 9 from both sides:

x = -3

Since this value of x is different from the previous two equations, we can conclude that it is not equivalent to them.

Now, let's move on to the fourth equation:

x + (-4) = 7

Add 4 to both sides:

x = 11

This value of x is also different from the first two equations, so it is not equivalent to them.

Finally, let's look at the fifth equation:

-5 + x = -2

Add 5 to both sides:

x = 3

Notice that we got the same value of x as the first two equations, so this equation is also equivalent to them.

So, correct options are A, B and E.

The probability of a student being female given that they got a 'B' is 87/315.

We can use Bayes' theorem to find the probability of a student being female given that they got a 'B'. Let's first find the total number of students who got a 'B':

Total number of students who got a 'B'

= 7 + 9 + 6 + 13 + 16 + 12

= 63

Out of these 63 students, the number of females who got a 'B' is:

Number of females who got a 'B' = 13 + 16 = 29

So, the probability of a student being female given that they got a 'B' is:

P(Female | B) = P(B | Female) x P(Female) / P(B)

From the given data, we can calculate these probabilities as follows:

P(B | Female) = 29/25

P(Female) = 25/63

P(B) = 63/175

Plugging in these values, we get:

P(Female | B)

= (29/25) x (25/63) / (63/175)

= 87/315

Therefore, the probability of a student being female given that they got a 'B' is 87/315.

To solve for the remaining sides and angles of the triangle, given two sides and an adjacent angle, use the Law of Sines formula:

Given values:

Substitute the given values into the formula and solve for angle B:

[tex]\implies \dfrac{a}{\sin A}=\dfrac{b}{\sin B}[/tex]

[tex]\implies \dfrac{14}{\sin 110^{\circ}}=\dfrac{9}{\sin B}[/tex]

[tex]\implies 14\sin B=9\sin 110^{\circ}[/tex]

[tex]\implies \sin B=\dfrac{9\sin 110^{\circ}}{14}[/tex]

[tex]\implies B=\sin^{-1}\left(\dfrac{9\sin 110^{\circ}}{14}\right)[/tex]

[tex]\implies B=37.1632517...^{\circ}[/tex]

[tex]\implies B=37.2^{\circ}[/tex]

As the interior angles of a triangle sum to 180°:

[tex]\implies A+B+C=180^{\circ}[/tex]

[tex]\implies C=180^{\circ}-A-B[/tex]

[tex]\implies C=180^{\circ}-110^{\circ}-37.1632517...^{\circ}[/tex]

[tex]\implies C=32.8367482...^{\circ}[/tex]

[tex]\implies C=32.8^{\circ}[/tex]

Finally, substitute the values of a, A, and C into the Law of Sines formula and solve for side c:

[tex]\implies \dfrac{a}{\sin A}=\dfrac{c}{\sin C}[/tex]

[tex]\implies \dfrac{14}{\sin 110^{\circ}}=\dfrac{c}{\sin 32.8367482...^{\circ}}[/tex]

[tex]\implies c=\dfrac{14\sin 32.8367482...^{\circ}}{\sin 110^{\circ}}[/tex]

Substitute the given values into the formula and solve for angle C:

[tex]\implies \dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

[tex]\implies \dfrac{21}{\sin 110^{\circ}}=\dfrac{13}{\sin C}[/tex]

[tex]\implies 21 \sin C=13\sin 110^{\circ}[/tex]

[tex]\implies \sin C=\dfrac{13\sin 110^{\circ}}{21}[/tex]

[tex]\implies C=\sin^{-1}\left(\dfrac{13\sin 110^{\circ}}{21}\right)[/tex]

[tex]\implies C=35.5712205...^{\circ}[/tex]

[tex]\implies C=35.6^{\circ}[/tex]

As the interior angles of a triangle sum to 180°:
