Question

Tell whether the angles are complementary or supplementary. Then find the value of x.

Answer 1

Explanation:

SUPPLEMENTARY because they are on a staright line and add up to 180°

`76 + (2x + 4) = 180 \\ 2x + 76 + 4 = 180 \\ 2x = 180 - 76 - 4 \\ 2x = 100 \\ (2x)/(2) = (100)/(2) \\ x = 50`

x=50°
