NO ONE IS HELPING PLEASE. Find the value of x in each case! IF U GET THIS I WILL MARK BRAINLIEST. 25 POINTS ON THE LINE! Thank y

Murrr4er [49]

Answer:

Step-by-step explanation:

Use corresponding angles.

Angle FBC is 180 - 147 which is 33.

This means x is 180 - 33 - Angle EBA.

EBA is 180 - 4x.

x = 180 - 33 - (180 - 4x)

x = 180 - 33 - 180 + 4x

-3x = 180 - 33 - 180

-3x = -33

3x = 33

x = 11

Please mark brainliest.
