    Points on a triangle

    Sorry, I think I posted this in the wrong section. Anyway... I have a problem and I can't figure it out. I have to points on a plane. One point is (0,0), the other point is (x,y). When I join these points the length of the line is 90. This line is used to make a right angle triangle with both angles (non right angles) pi/4. How do I figure out the points (x,y) using SIMPLE trig? Any help is greatly appreciated. Cheers.

    Note that the triangle is isosceles so x=y.
    y = \left( {90} \right)\sin \left( {\frac{\pi }{4}} \right)
