9)In hABC, MAA=49D,a=33,and c=25 find measure of acute AB

Answer 1

Why don't you post your answers?  It would take too long for me to explain all of them, but if I only had to correct the wrong ones, it would be much quicker.

Anyway, here's the first one.

We know sinC/c = sinA/a

Plug in what we are given.

(1/4)/6 = sinA/12

Simplify.

1/24 = sinA/12

Multiply both sides by 12.

1/2 = sinA
