Answer:
1=101 4=79 2=79
Explanation:
Angle 3 is given as 101. The angle across from it has to be the same angle measure so angle 1 is 101. Because the angle 4 added to 3 is a straight line or 180 degrees (half a circle) than you just have to subtract angle 3 from 180 to get angle 4 which is 79. Angle 4 and angle 2 have to be the same so angle 2 is 79. I hope this helps
