first you have to distribute to the parentheses to get 6a + 30=8a-24-8a simplify for 6a + 30 = -24 then - 30 on both sides to move it for 6a = -54 divide both by 6 to get a = 9

Vertical angles are equal

-3x + 58 = x - 2
-3x - x = -2 - 58
-4x = - 60
x = -60/-4
x = 15

m < D = x - 2....15 - 2 = 13 <====
m < C = -3x + 58....-3(15) + 58 = 13
