Answer: By using the property of the triangle, we can easily find the solution
We can use the concept whereby angles opposing equal sides are also equal and then we can find the value of B AND C
AS STATED,
AB=AC
∴ ∠C =∠B
So let ∠B=∠C = x
So ∠A + ∠B+ ∠C=180° (sum of an angle property of a triangle)
Or, 90°+x+ x = 180°
Or, 90° +2x = 180°
Or 2x = 180°
So, x = 45°
∴ ∠C=∠B = 45°
