Pls help I’ll give points

Answer 1

• m∠EBC = 65°15'
• AC = 20 in

Explanation:

ΔABC is isosceles. Since BE ⊥ AC, it is the bisector of ∠ABC. Then ...

m∠EBC = (1/2)·m∠ABC = (1/2)·130°30'

m∠EBC = 65°15'

___

BE is not only the bisector of ∠ABC, it is also the median from vertex B. That is ...

AC = 2·AE = 2·10 in

AC = 20 in
