Hello!
Answer:

|2x - 5| = 4
Solve for the negative and positive expressions:
2x - 5 = 4
2x = 9
x = 9/2
------------
-(2x - 5) = 4
-2x + 5 = 4
-2x = -1
x = 1/2.
Therefore, the solutions are x = 1/2 and 9/2.
Something I noticed about angle 4, is that it shares a straight line with angle 3. (above it is a straight line)
A straight line equals 180 degrees.
So, angle 4 + angle 3= 180 degrees.
Angle 3 is congruent to angle 7.
180-132= Angle 7
180-132= 48
48 degrees is your answer.
I hope this helps!
