Question

Find the measures of the angles of a triangle if the angles are resented by x, 4x, and 4x. show work

Answer 1

x = 20

Explanation:

Total degrees of a triangle = 180 degrees.

The three angles are x, 4x & 4x

x + 4x + 4x = 180 degrees

x + 8x = 180 degrees

9x = 180 degrees

(9x)/9 = 180/9

x = 180/9

x = 20
