If m∠ebd= 4x - 8 and m∠ebc= 5x + 20, find the value of x and m∠ebc.

-28 = x

Step-by-step explanation

[5x + 20] + [4x - 8] = 180

9x + 12 = 180

- 12-12

9x = 168

18⅔ = x

m∠EBC = 5[18⅔] + 20 = 113⅓

93⅓

You will get a negative answer if you set them equal to each other, which is not allowed when you are talking about length.

I hope this is correct, and as always, I am joyous to assist anyone at any time.
