The measure of the angle is 30.00 degrees

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right triangles. It is concerned with the measurement of angles and the calculation of sines, cosines, and tangents of those angles.

These ratios are known as trigonometric functions and they are used to relate the ratios of the sides of a right triangle to the angles opposite or adjacent to the right angle.

Since sin 30° = 0.5

Thus, sin⁻¹(0.5) = 30.00 degrees

Note: Angle 30° is one of the special angles and trigonometric are very easy recall.

Answer:

9 and 10

Step-by-step explanation:

66 divided by 7 would be 9.4 which lies between 9 and 10.

Area of the triangle DEF = 35 square unit.

A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.

Given,

Vertices of triangle

D(4, -3), E(-2, 1), and F(-9. -6)

   x₁  y₁      x₂ y₂              x₃ y₃

Area of triangle S = 1/2[x₁(y₂−y₃)+x₂(y₃−y₁)+x₃(y₁−y₂)]

Area of triangle DEF = 1/2[4(1 - -6) + -2(-6 - -3) + -9(-3 - 1)]

                                  = 1/2 [4(7) -2(-3) -9 (-4)]

                                  = 1/2[28 + 6 + 36]

                                  = (1/2) (70)

Area of triangle DEF = 35 square unit

Hence, 35 square unit is the area of triangle DEF.

Using Trigonometric identities, the value of y = 11.49.

Trigonometric identities are equality conditions in trigonometry that hold for all values of the variables that appear and are defined on both sides of the equivalence.

These are identities that, geometrically speaking, involve certain functions of one or more angles.

They are not to be confused with triangle identities, which are identities that may involve angles but may also involve side lengths or other lengths of a triangle.

Using Trigonometric Identities,

Cos θ = Base / Hypotenuse

Cos 29 = 10 / y

0.87 = 10 / y

y = 10 / 0.87

The exponential form of 10 * 10 is [tex]10^{2}[/tex] . We get it from the prime factorization.

In order to get the exponential form of a number we have to write the prime factorization of that number. Prime factorization of the number is that number written as a product of prime numbers or as a product of powers of prime numbers. A basic exponential function from its definition is of the form f(x) = b x, where 'b' is a constant and 'x' is a variable. generally it refers to the positive valued function of a real variable. We can find the prime factorization of a number using factor trees, which are tools used to repeatedly break a number into products until all of the factors are prime numbers.

A polynomial is a kind of algebraic expression in which the exponents of all variables should be a whole number.

The Power of the variables in any polynomial has to be a non-negative integer. A polynomial consists of constants and variables, but we cannot perform division operations by a variable in polynomials.

The example of polynomial is: 3x^2 + 5.

With sides that are 4 cm, 3 cm, and 7 cm long, a triangle cannot be built. Because the sum of the other two sides does not exceed that of the third side.

A triangle is referred to as a three-sided polygon that has three vertices. The connection of the three sides ends to end at a single point forms the angle of the triangle. The sum of these angles adds up to 180 degrees.

The triangle's three sides are specified as being 4 cm, 3 cm, and 7 cm. Add the two sides together and see if the result exceeds the third side to determine whether these sides constitute a triangle.

Here, the sum of two sides 4 cm and 3 cm is calculated as,

A+B = 4+3

=7 cm

This sum is equal to the third side C = 7 cm.

Therefore,  [tex]A+B\ngtr C[/tex]. So, the given sides don't form a triangle.

Step-by-step explanation:

Answer:

A linear equation can be used to represent the situation where a fixed amount is added to the original balance each month. The equation would have the form:

y = mx + b

where x is the number of months, y is the balance in the bank account, m is the monthly deposit amount, and b is the initial balance. In this case, we have:

y = 60x + 575

This equation can be read as: "The balance in the bank account (y) is equal to 60 dollars (m) added to the account each month (x), plus the initial balance of 575 dollars (b)."

An exponential equation can also be used to represent the situation where the balance in the bank account increases by a fixed percent each month, it would be:

y = a(1+r)^x

The solution to the given system of linear equations is x = -4, y = -10

From the question, we are to solve the given system of linear equations.

The given system of linear equations is

y = 2x - 2          ------------ (1)

-4x - y = 26     ------------ (2)

Substitute equation (1) into equation (2)

-4x - y = 26

-4x - (2x - 2) = 26

- 4x - 2x + 2 = 26

-6x + 2 = 26

-6x = 26 - 2

-6x = 24

x = 24/-6

x = -4

Substitute the value x into equation (1)

y = 2(-4) - 2

y = -8 - 2

y = -10

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

Initial amount in the club account = m

Amount raised by each member = n

All members raised the same amount.

Number of members = x

The total amount raised by all the members = p

nx + m = p

This is similar to the equation 300x + 750 = 23,250

So,

n = 300

m = 750

p = 23,250
