I think it helps you a lot

Answer 2

45°

Step-by-step explanation:

Given

ABC is an isosceles right angle triangle

A = 90

B = C ( since ABC is an isosceles triangle)

let B and C be x

A + B + C = 180 (ANGLE SUM PROPERTY)

90 + X +X = 180

2x + 90 = 180

2x = 180-90

2x = 90

x = 90/2

x = 45°

therefore B =C = 45 °
