Answer:
x = 25
Explanation:
To solve this, you would have to set up an expression using the information they gave you.
We know that the total measure of the angle is 5x - 8, so everything else within the angle should add up to 5x - 8:
3x + 22 + 20 = 5x - 8
the expression 3x + 22 represents angle GED and the 20 is the measure of angle FEG
Now to solve
3x + 22 + 20 = 5x - 8
3x + 42 = 5x - 8
42 = 2x - 8
50 = 2x
25 = x
