Dear Mr. X. In any case we need inverse trigonometric functions. To
less complicated calculations, you can assume that angle lies in the
certain region of unit circle such that cos(angle)=3/5, sin(angle)=4/5
and regard other cases.

See, the thing is that we haven't learnt inverse ratios yet, so is
there any way to solve it without using inverse trigonometry?
