ok so can anyone explain this one to me? do we use the sine rule to find the angle of elevation? cause i did this:
18/sin15 = 20/sin x .... were x is the angle we gotta find.
it gave me an answer of 16 degrees....but apparently the answer is 56.
what am i doing wrong?? am i looking at the wrong angle?
also my calc is set to deg not rad.
