I've been trying to solve a right triangle, and Im getting nowhere. Its been a while since I've studied trig, so I've forgotten alot of things.

The triangle Im working on, I only know the Opposite side which is 4700m, and the hypotenuse which is (1.75m + another number). No angles are given, except the obvious 90 degree angle that

is in every right angle triangle. If someone could point me in the right direction it would be much apprecieted.
