    let's do the first triangle, in the first triangle we a right angle which is 90 degrees, now given the info from the problem we can now solve this by thinking about sin, cos , tan here.

    okay no prob. you have all you need to do this problem, notice on the choices give they refer to to the triangles listed on the picture so now what we have to is look at if we use sin,cos or tan in these cases to solve
