In $$\triangle$$ABC, AB = AC, and $$\angle$$BAC is 50$$^\circ$$. Then $$\angle$$ABC and $$\angle$$BCA are, respectively:
In $$\triangle$$ABC, Â AB = AC
Angles opposite to equal sides in triangle are equal.
$$\Rightarrow$$Â $$\angle$$BCA =Â $$\angle$$ABC
Let $$\angle$$ABC = $$\angle$$BCA = x
In $$\triangle$$ABC,
$$\angle$$ABC +Â $$\angle$$BCA +Â $$\angle$$BAC =Â 180$$^\circ$$
$$\Rightarrow$$Â x + x +Â 50$$^\circ$$ =Â 180$$^\circ$$
$$\Rightarrow$$Â 2x =Â 130$$^\circ$$
$$\Rightarrow$$Â x =Â 65$$^\circ$$
$$\therefore\ $$Â $$\angle$$ABC = $$\angle$$BCA =Â 65$$^\circ$$
Hence, the correct answer is Option B
