Question

What is beta and alpha? I need ASAP

Answer 1

alpha: 53.13°

beta: 36.87°

Explanation:

sin(theta) = opposite/hypotenuse

sin(alpha) = 12/15 = 0.8

alpha = sin^-1(0.8)

alpha = 53.130102354

beta = 90 - alpha

beta = 90 - 53.1301023542

beta = 36.8698976458

Answer 2

see below

Explanation:

Since this is a right triangle, we can use trig functions

sin alpha = opp side/ hyp

sin alpha = 12/ 15

Take the inverse sin of each side

sin^-1 sin alpha = sin^-1 (12/15)

alpha = 53.13010235

sin beta = opp side/ hyp

sin beta = 9 /15

Take the inverse sin of each side

sin^-1 sin beta = sin^-1 (9/15)

beta = 36.86989765
