Question

Find the value of x in each case (Need these by Nov. 1st -- tomorrow). (Will mark brainliest if you're helpful ... THANK YOU!!!!!)

Answer 1

Answer:

1 answer :-x = 15 degrees.

Step-by-step explanation:

m < CBA = 180 - 9x   (Adjacent angles).

By the External Angle of a Triangle theorem:

8x = 5x + (180-9x)

8x = 5x - 9x + 180

8x = -4x + 180

12x = 180

x = 15.

Answer 2

Answer:

A) 8x + 9x (180-5x) =360

x=180/12

x= 15
