Question

How am I supposed to do this? I know that the x = 11, but I have no clue on what to do from there

Find m∠CED.

Answer 1

Answer: 140°

Explanation:

x = 11

5 x 11 = 55

55 - 15 = 40

The 5x-15 = 40°

tHe 3x+7 is opposite, so it also equals 40°

40 + 40 = 80°

360° - 80° = 280

280 divided by 2 = 140°
