Question

I need help im gonna get saturday school if i dont finish all my missing work(failing math)

Answer 1

Explanation:

sum of the interior angles of a triangle = 180

90 + (5x - 6) + 3x = 180

8x + 84 = 180

8x = 180 - 84 = 96

x = 96/8 = 12

D = 5(12) - 6 = 54

E = 3(12) = 36

F = 90

54 + 35 + 90 = 180 answers are correct!
