Question

What are all the missing angles?

Answer 1

E is 49 because they are opposite angles. F is 180 - 49 = 131

Answer 2

d = 90 degrees

e = 49 degrees

f = 131 degrees

Explanation:

angle d is 90 degrees because adjacent angles add to 180 degrees, if the adjacent angle is right it is equal to 90 degrees, 180 - 90 is 90.

angle e is 49 degrees because opposite angles are equivalent.

angle f is 131 because adjacent angles add to 180 degrees, if the adjacent angle is 49, 180 - 49 is 131.
