Answer:(d)
Step-by-step explanation:
Given
AB=AC
We can write
![\angle ABC=\angle ACB\ \quad \text{[angles corresponding to equal sides are equal]}](https://tex.z-dn.net/?f=%5Cangle%20ABC%3D%5Cangle%20ACB%5C%20%5Cquad%20%5Ctext%7B%5Bangles%20corresponding%20to%20equal%20sides%20are%20equal%5D%7D)

Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
