Pythagoras discovered many of the properties of what would become trigonometric functions. The Pythagorean Theorum, a2 + b2 = c2 is a representation of the fundemental trigonometric identity sin2(x) + cos2(x) = 1. 1 is the hypotenuse of any right triangle, and has legs length sin(x) and cos(x) with x being one of the two non-right angles. With this in mind, the identity upon which trigonometry is based turs out to be the Pythagorean Theorum.

What describes Pythagoras' contribution?
Discover of a Mathematical formula to relate the sides of a right triangle.
Why is Pythagoras' theorem useful?
well... one of its uses can be as follows: you see trigonometry deals with right angles right, so through the Pythagoras theorem you can find out the sides of the triangle, without which trig would be impossible!
