If m∠F=116 , find m∠E
a)32
b)64
c)116
d)58

Answer 1

a)32?

Answer 2

Almost magic. How did you arrive at 32º?

Answer 3

it must add to 180

Answer 4

That's not quite enough information.

180 - 116 = 64. I'll give you that. Now, how shall we split up these 64º? Are we SURE they are equal and each is 32º? How can you get sure or prove otherwise?

Answer 5

because d and e are congruent divide 64 it's 32 so a....

Answer 6

Correct. 32 degrees.

Answer 7

It is easy enough to SAY that d and e are congruent. You have not stated how you KNOW they are congruent.
