Question

Two of the angles in a triangle measure 13° and 5°. What is the measure of the third angle?

Answer 1

162

Explanation:

The total amount of degrees a triangle can have is 180. This means that

13 + 5 + x = 180

Solve for x.

13 + 5 + x = 180

18 + x = 180

(18 + x) - 18 = 180 - 18

x = 162

The angle's measure will be 162 degrees.
