Question

In right triangle ABC, ∠C is a right angle and sin A = sin B. What is m∠A? 30° 45° 60° 75°

Answer 1

Answer:

m<A = 45°

Step-by-step explanation:

Given ABC is a right angled triangle.

m<C = 90°

Therefore,

<A + <B = 90° ---(1)

sinA = sinB (Given)

=> A=B ---(3)

Substitute (3) in equation (1), we get

<A+<A = 90°

=> 2<A = 90°

=> <A = 90°/2

=> <A = 45°

Therefore,

m<A = 45°
