(Sat prep) find the value of x, 65 degrees and 75 degrees isosceles triangle.

Answers

Answer 1

Answer:

x = 40°

Step-by-step explanation:

The triangle is not isosceles

The angles of the triangles are:

65°, 75° and x for both of the bigger and the smaller triangles

The interior angles of a triangle sum to 180

x = 180° - (65° + 75°)x = 180° - 140°x = 40°

A painter is placing a ladder to reach the third story window, which is 14 feet above the ground and makes an angle with the ground at 70°

How far out from the base of the building does the ladder need to be positioned? Round your answer to the nearest tenth.

Answers

Answer:

4.8

Step-by-step explanation:

We are given the hypotunese or the slanted side which is the ladder length which is 14.

We are given an angle at the bottom which is 70 degrees.

We are asked to find the horizontal side which is adjacent to the angle at the bottom.

Since we have a hypotunese and a side adjacent to the angle, we are going to use the function cosine.

we use this formula

[tex] \cos(theta) = \frac{adj}{hypo} [/tex]

[tex] \cos(70) = \frac{x}{14} [/tex]

32) In a triangle, the exterior angle is twice of each of the interior remote angles. The exterior angle is 1200. Find the measure of the three angles of the triangle.

Answers

Answer:

60 degrees each

Step-by-step explanation:

For the triangle, the sum of the interior angles is equal to the exterior

Let x and y be interior

Let z be the third angle

w be the exterior

w = x+y

120 = x+y

If the exterior angle is twice of each of the interior remote angles, then;

2x = 2y

x = y

120 = x+x

2x = 120

x = 60

Since x = y, y = 60 degres

From the triangle, the third angle will be 180 - 120

z = 180-120

z = 60

The measures of the 3 angles are 60 degrees each

C.
(280 + 7) ÷ (7 + 7)
D.
(280 ÷ 7) + (280 ÷ 7)

Answers

Answer:

(280+7) ÷ (7+7)

Step-by-step explanation:

hopefully this helps ya

The equation that is equal to 287 ÷ 7 is (280 + 7) ÷ (7 + 7). The correct option is C.

What is equation?

An equation is a statement in mathematics that shows that two expressions are equal. It has two sides that are separated by an equal sign.

To find the value of 287 ÷ 7, we can use the following methods:

(280 ÷ 7) + (7 ÷ 7) = 40 + 1 = 41(280 ÷ 7) - (7 ÷ 7) = 40 - 1 = 39(280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5(280 ÷ 7) + (280 ÷ 7) = 40 + 40 = 80

We can simplify 287 ÷ 7 as follows:

287 ÷ 7 = 280 ÷ 7 + 7 ÷ 7

Note that 7 ÷ 7 simplifies to 1, so we have:

287 ÷ 7 = 280 ÷ 7 + 1

Therefore, the answer is C. (280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5.
