Answer:

45°

Step-by-step explanation:

In triangle ABC, AB = AC. [since any other pair can't be equal]

Therefore, angle B = angle C [ angles opposite to equal sides in a triangle, are equal]

It is given that angle A = 90°

Now, angle A + angle B + angle C = 180° [angle sum property of a triangle]

=> 90° + angle B + angle B = 180° [ since angle B = C]

=> 2 angleB = 180° - 90°

=> angle B = 90°/2

=> angle B = 45° = angle C
