Step-by-step explanation:
If CD and DE equal, then x+6 = 4x -21
So if you subtract x from both sides and plus 21 to both sides, that would be 3x = 27. Divide by 3 on both sides and you get 9.
Plug in x+6 with 9 and you get 15.

Same-side interior angles are supplementary, meaning that they add up to 180 degrees.
5x + 34 + 2x + 76 = 180
7x + 110 = 180
7x = 70
x = 10
Measure of angle A = 5(10) + 34 = 84 degrees
Hope this helps!! :)
