Step-by-step explanation:
If angle 1 is 121 degrees, then angle 7 is 59 degrees. (same side exterior angles)
If angle 8 is 103 degrees, then angle 4 equals 103 degrees (corresponding angles) and angle 3 is 77 degrees. (to angle 4 supplementary angles)
If angle 5 is 116 degrees, then angle 3 is 64 degrees. (same side interior angles)
