Answer:

90 degrees

Step-by-step explanation:

10 + 3 + 7 = 20

10/20 x 180 = 90 degrees

Hope this helped :)

Answer:

The largest angle is 90 degree[10]

Step-by-step explanation:

Let 10:3:7 be x

10x+3x+7x = 180 [ angle sum property of a triangle ]

20x = 180

x=180/20

 =9/1

 =9

10x=10*9=90

3x=3*9=27

7x=7*9=63

90>63>27

therefore the largest angle is 90 degree.

Answer:

236

Step-by-step explanation:

number of chairs left = total chairs - 7 chairs

total chairs = 9 × 27

= 243

243 - 7

= 236

Answer: 236

Step-by-step explanation:

We have to figure out how many chairs there are in total so you will do 9*27. That is 243. If 7 were removed, you would do 243-7 which is 236. Therefore, there are 236 chairs left.

The coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis include the following:

P" = (-4, 0).

Q" = (-(3), 1) = (-3, 1).

R" = (1, -2).

In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of triangle P′Q′R′, the coordinates of triangle P′′Q′′R′′ include the following:

(x, y)                               →              (-x, y)

Coordinate P' = (4, 0)   →  Coordinate P" = (-(4), 0) = (-4, 0).

Coordinate Q' = (3, 1)   →  Coordinate Q" = (-(3), 1) = (-3, 1).

Coordinate R' = (-1, -2)   →  Coordinate R" = (-(-1), (-2)) = (1, -2).

The required highest common factor of 25, 75, and 150 is 25.

The highest common factor (HCF) of two or more numbers is the largest number that divides all of the numbers exactly.

To find the HCF of 25, 75, and 150, we can first find the prime factorization of each number and then look for the common factors.

Prime factorization of 25,  25 = 5²

Prime factorization of 75:, 75 =  5² × 3

Prime factorization of 150,  150 = 2 × 3² × 5²

The largest factor that all three numbers have in common is 5², which is 25.

x^2 + (y – 3)^2 = 36

Step-by-step explanation:

The standard equation of a circle with center at (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2.

If the center lies on the y-axis, then h = 0:  (x - 0)^2 + (y - k)^2 = r^2

If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36

So, among the given equations, your

x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).

In the triangle  ΔJKL,  the length of side k found using the law of cosines is approximately 1764 inches.

What is meant by the law of cosines?

The law of cosines, commonly referred to as the cosine formula or cosine rule, is a relation in trigonometry that links the lengths of a triangle's sides to the cosine of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them.

If ABC is a triangle, then as per the statement of cosine law,  we have:

c = [tex]\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]

where,

c = length of side c

a = length of side a

b = length of side b

γ = angle opposite c

Given a triangle, ΔJKL

The length of side l= 920 inches

The length of side j = 880 inches

∠K = 157°

According to the law of cosines,

k² = l² + j² - 2.l.j . cos K

  = 920² + 880² - 2 * 920 * 880  * cos (157°)

=  846400+ 774400 - (-1490481.46)

= 3111281.46

k = 1763.88 = 1764 inches.

Therefore the length of side k found using the law of cosines is approximately 1764 inches.

The Option that is common to the formation of all fossil fuels is: fossils are converted into carbon-rich fuels. The Option A is correct.

Fossil fuels are gotten from the decomposition of plants and animals. These fuels, which can be found in the Earth's crust and contain carbon and hydrogen, can be burned for energy. Fossil fuels include coal, oil, and natural gas.

Coal is a material that is typically found in sedimentary rock deposits where layers of rock and dead plant and animal matter are piled up. More than half of the weight of a piece of coal must come from fossilized plants. Oil was discovered as a solid material between layers of sedimentary rock, such as shale.

Answer:

the face value of the loan is $5,263.16.

Step-by-step explanation:

To determine the face value of the loan, we need to use the formula:

Face Value = Proceeds / (1 - Discount Rate * Time)

where "Time" is the time period of the loan in years.

Since the loan is for 6 months, we need to convert this time to years by dividing it by 12. Therefore, "Time" = 6/12 = 0.5 years.

Now, we can substitute the given values into the formula:

Face Value = 5,000 / (1 - 0.1 * 0.5)

Face Value = 5,000 / (1 - 0.05)

Face Value = 5,000 / 0.95

Face Value = $5,263.16 (rounded to the nearest cent)

Therefore, the face value of the loan is $5,263.16.

Answer:

Step-by-step explanation:

Given: In triangle ABC, AB = AC and D is the midpoint of BC.

To prove:

i) AD is perpendicular to BC.

We can prove this by using the midpoint theorem, which states that a line segment connecting the midpoints of two sides of a triangle is perpendicular to the third side and half as long as the third side.

Since D is the midpoint of BC, we have BD = DC. Thus, the line segment AD connects the midpoints of sides AB and AC of triangle ABC.

By the midpoint theorem, AD is perpendicular to BC and AD = BC / 2.

ii) AD bisects angle BAC

We can prove this by using the fact that if two line segments are perpendicular and one is an altitude of a triangle, then the two line segments divide the triangle into four smaller triangles that are congruent by SAS congruence.

Since AD is perpendicular to BC, we have two right triangles, ABD and ACD. By the Pythagorean theorem, we have AB = AC, which means that ABD and ACD are congruent by SAS congruence.

Since ABD and ACD are congruent, we have angle BAD = angle CAD. Also, since angle BAC is the sum of angles BAD and CAD, we have angle BAC = 2 * angle BAD.

Therefore, by substitution, we have angle BAC = 2 * angle CAD. This means that angle CAD is half of angle BAC, or in other words, AD bisects angle BAC.

Hence, we have proved that in triangle ABC, AD is perpendicular to BC and AD bisects angle BAC.

The required y-coordinate of system of equation is -3.

The second component of an ordered pair is a y-coordinate. The y-coordinate denotes the directional separation of the point from the x-axis when an ordered pair is graphed as the coordinates of a point in the coordinate plane. The ordinate is another term for the y-coordinate.

We have,

y = x/2 - 4 and y = -2x + 1

Equate both equation

x/2 - 4 = -2x + 1

x - 8 = -4x + 2

5x = 10

x = 2

Then,

y = -2x + 1

y = -2(2) + 1

y = -4 + 1

y = -3

Thus, required y-coordinate of system of equation is -3.
