State the related acute angle for sin(-π/3) and then find the exact value
I am getting 60 degrees, is this correct?

actually, -60º ... what's the sine?
I'm not sure you mean when you say "what is the sine"
the question asks for the angle and "the exact value" of the sine
That's what I'm asking about, I'm not sure what the "exact value" is. In fact, I'm not really sure if I've got the right "related acute angle"
sin - 60 = - (1/2) sqrt 3
1, sqrt 3 , 2 right triangle
