Hey guys 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.
