Plz answer this step by step ​

Answer 1

Step-by-step explanation:

We have,

ext. angle CBD = ACB + ABC

-> 1/2 CBD = 1/2ACB + 1/2ABC

-> EBC = EAC + 1/2ACB ------- (i)

In triangle ABE, we have,

ext. angle EBD = EAC + AEB --------(ii)

From (i) and (ii), we get

EAC + 1/2ACB = EAC + AEB

-> 1/2 ACB = AEB

Therefore, AEB = 1/2 ACB
