Question

Given that ABC = DEF, find the measure of 13 years ago

Answer 1

Since both are equal, A = 60 & E = 40.
60+40=100.
180-100=80.
So the answer would be 80. would that be right?

Answer 2

80

Answer 3

Alright, thanks, I wasn't sure if I had to subtract from 180.

Answer 4

the sum of interior angles for a triangle is always 180. so you were right :) good job

Answer 5
