Question

If m∠BEG = 54° and m∠BEA = 27°, then m∠AEG = _____.

A) 135°
B) 27°
C) 90°
D) 81°

Answer 1

∠BEG and ∠BEA both share the common side B and the common corner E. That means they are adjacent angles. Together, they create a big angle, ∠AEG. To find the angle measurement of ∠AEG, you can just add up the measurements of the two adjacent angles, ∠BEG and ∠BEA:
54° + 27° = 81°.

That means ∠AEG = D) 81°.

Answer 2

You would add them.
So, 54+27=81
D) 81 degrees is your answer :)
