I would really appreciate if someone could explain the process to solve it

x = 12°

Detailed explanation down below.

Step-by-step explanation:

Ill be delighted to help

8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

In this situation, those two angles are 30° and 4x+2°

So lets put this in an equation

30° + 4x + 2° = 8° + 6x

4x + 32° = 6x + °8

Now lets subtract 8° from both sides to make it simpler

New equation =

4x + 24° = 6x

Lets evaluate X=

6x - 4x = 24°

2x = 24°

x= 24/2

x= 12°

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
