Can some one me with some math problems

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

Acircular city park has a sidewalk directly through the middle that is 111 - feet long. if each bag of fertilizer covers 50 square feet, then determine how many bags of fertilizers the parks and recreation department needs to use to cover the circular park. ignore all the sidewalks around and through the park.

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.
