Given: In triangle ABC, AB=BC and C's measure is 65°.

Asked: What is the measure of angle B?

AB=BC => Angle A = Angle C = 65°
For a triangle, sum of all 3 angles = 180°
2*65+B = 180
B=50°

IMO B

Since the triangle is an isosceles triangle(AB = BC). Angles opposite to sides AB(∠C) and BC(∠A) would also be equal. We need to find ∠B.
As, ∠C = 65⁰
 ∠B = 65⁰

We know sum of all the angles of a triangle = 180⁰
 ∠A + ∠B + ∠C = 180⁰
 ∠B = 180⁰ - (∠A + ∠C)
 ∠B = 180⁰ - (65⁰ + 65⁰)
 ∠B = 180⁰ - 130⁰
 ∠B = 50⁰

Answer (B)
