Question

In right triangle ABC, ∠C is a right angle and sin A = sin B. What is m∠A?

A) 30°

B) 45°

C) 60°

D) 75°

Answer 1

it means <A = <B
A+B+C=180
A+A+90=180
solve for A

Answer 2

Soo.. Whats the answer?

Answer 3

have you tried first ?

Answer 4

Yesssss

Answer 5

it means <A = <B
A+B+C=180
A+A+90=180

abc will equal 180 because its a triangle
A+B+C=180
we already know there is a 90 degree angle so we will put 90 for B
A+90+C=180
you need to reach 180
in a right triangle two angles are the same so half of 90 is 45
45+90+45=180 so the answer is 45 degrees
