If the measure of angle 4 is 132 ,what is the measure of angle 7?
Mnenie [13.5K]
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:)
