Question

△ABC, ∠ABC = 90° and AB = BC. Then ∠A = …….​

Answer 1

Answer:

45°because if 1 angle is 90° than othe two will be 45,45

Answer 2

Here is your Answer:-

AB = BC

=> ∠C = ∠A

Let say ∠A = x

=> ∠C = X

∠A + ∠B + ∠C = 180° ( sum of angles of triangle)

=> x + 90° + x = 180°

=> 2x = 90°

=> x = 45

∠A = 45°
