Question

In this diagram, m ACB = 65. Find each of these.
1. m ECD
2. m ACE

Can someone show me the steps? I want to learn how to do this.

Answer 1

ACD = 90, BCD = 25, so ECD is 180 - 25 = 155, ACF = 90, ECF = 25

Answer 2

Thanks.

Answer 3

So it's the same answer for both? That's what I calculated at least.
