1. •Exterior angle is the sum of the two interior opposite angles
   A) 1x + 1x = 100
   2x = 100
   x = 100/2
   x = 50
   Angles are 50 and 50 ( 1x = 1*50)
   B) 3x + 2x = 100
   5x = 100/5
   x = 20
   Angles are 60 (3*20) and 40 (2*20)
   C) 1x + 3x = 100
   4x = 100
   x = 100/4
   x = 25
   Angles are 25 and 75
