if ray EB bisects angle AED, EC bisects angle BED, and the measure of angle BEC=30, find measure of angle AEC?
- 1 decade agoFavorite Answer
angle AEC is 90, because BEC is 30 + BED= 60, whch means angle AEB=60 & 60+30=90Source(s): i recently did this exact same problem in my math class

the best thing is to first draw a picture. Unfortunately I can't here.
since angle BEC=30, the CED also is 30. Now you know BED is 60, so AEB is 60. so add AEB to BEC and you will have AEC =90.

EB is the bisector of <BED and given <BEC=30
again <AEB=60 ,EB bwubf th biawctor of <AED

<CED = <BEC = 30
So <BED = 60 = <AEB
So <AEC = <AEB + <BEC
= 60 + 30
= 90Source(s): Me ;^))

BEC = 30
BED = 60
AEB = 60
AEC = 90
