Answer:

53

Explanation:

angle 2 and 3, angle 3 and 4 are both supplementary angle, which means a2+a3=180 degree, a3+a4=180 degree.

Since you know that the angle 2 and 4 are both 29 degree,

you can write

a3+29=180, and a3 is represented as 3x-8

so

(3x-8)+29=180 (<-- answer for b)

3x+21=180

3x+21-21=180-21

3x=159

x=53
