Question

Find the value of x. Then find the angle measures of the polygons

Answer 1

x = 43

Explanation:

The sum of angles in a triangle is equal to 180.

x + 2x + x + 8 = 180 add like terms

4x + 8 = 180 subtract 8 from both sides

4x = 172 divide both sides by 4

x = 43

To find the measure of each angle, replace x with 43
