    Help with trig problem. (solving right triangle)

    I have just started Trig, since it was at the end of my geometry book. I am studying with a practice test, and I have come to a problem that wasn't in my book. They had similar problems, but not one like it, and since there are so many rules with geometry and trig I wasn't sure how to solve this. I would be grateful for some help please!

    *Figure is a right triangle

    Question: Given the Figure below (right triangle), find ,
    a if sin B = 0.42, cos B = 0.91, tan B = 0.47 and c =60

    Figure,



    The triangle in the image is just like the one on my practice test, except it is flipped in the opposite direction if that make a difference, I don't know? A is facing the right on my practice test.

    Thank you!

    \cos{B} = \frac{a}{c}
