Answer:
50 degrees
Step-by-step explanation:
since angle bac is bisected, bae and eac are equal measurement. therefore:
x+30 = 3x-10
now isolate the variable
x-3x=-10-30
-2x=-40
2x=40
x=20
mEAC =3x-10
=3(20)-10
60-10
=50
this can be proven because BAE is the same measurement as EAC (because of the bisector): x +30
20+30
=50
