Answer:
e = 72; f = 108; d; 90
Explanation:
Since d is next to a right angle and the one next to it is a 90 degree angle, and it shows a 180 degree angle 180- 90 = 90. If an angle is opposite to another angle it is the same angle as the one opposite to it e = 72. F is 108 degrees because since that angle is equal to 180 degrees 180 - 72 = 108 degrees.
