Find tan if sin 34 and lies in quadrant III Can you provide

Find tan if sin = -3/4 and lies in quadrant III.

Can you provide me with the step by step process so that I can understand this question please?

Solution

sin theta=-3/4

Opposite=3

Hypotenuse=4

adjacent =sqrt(16-9) =sqrt 7

tan theta=opposite/adjacent =3/sqrt7
