Answer:
Angle e is 61
Angle f is 119
Angle d is 90
Step-by-step explanation:
When two lines meet, the opposite angles are the same, so e is 61. On a straight line, there are 180 degrees, so angle f would be 180-61=119. Angle d uses the same method, the square in the bottom right tells you one side is 90, so for the other side you take 180-90, and you get 90.
