What are the angle measures of triangle abc? m∠a = 30°, m∠b = 60°, m∠c = 90° m∠a = 90°, m∠b = 60°, m∠c = 30° m∠a = 60°, m∠b = 90°, m∠c = 30° m∠a = 90°, m∠b = 30°, m∠c = 60°

The correct option is:   m∠A = 90°, m∠B = 60°, m∠C = 30°

Explanation

Given sides of the triangle are....

Opposite side of ∠A is:  

Opposite side of ∠B is:   and

Opposite side of ∠C is:  

For finding the angles of triangle ABC, we need to use the Cosine rules. So....

So, the measures of ∠A, ∠B and ∠C are  90°, 60° and 30° respectively.
