a.95.8
b. 92.9
c 91.2

Answer 1

The value of x is 91.2 degrees if Larry is reroofing his house. each side of the roof measures 14 feet from the eave to the ridge.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a triangle shown in the picture:

We can find the angle using cos law:

$\rm cosx = \dfrac{14^2+14^2-20^2}{2\times14\times14}$

After solving:

$\rm cosx = \dfrac{-1}{49}$

x = 91.2 degree

Thus, the value of x is 91.2 degrees if Larry is reroofing his house. each side of the roof measures 14 feet from the eave to the ridge.
