Answer 1

Answer:

If in triangle ABC, AB = AC and ∠A = 50° then ∠B and ∠C are 65°.

Step-by-step explanation:

Given:

∠A = 50°

And AB = AC

Then opposite angle of sides are also equal

∠C = ∠B

Let if ∠C = ∠B = x

Sum of angles of triangle is 180 degree.

So, ∠A + ∠B + ∠C = 180°

50° + x + x = 180°

2x = 180 - 50 = 130°

x = 65°

So, ∠B = ∠C=65°
