1. The problem statement, all variables and given/known data The rectangular and polar coordinates of a point are (x,y) and (r,theta) where x = 7 and theta = 52 degrees. Determine r and y. 2. Relevant equations r = srt(x^2 + y^2) theta = arctan(y/x) x = rcos(theta) y = rsin(theta) 3. The attempt at a solution I tried to assume that r and x would be the same, so I let r = 7, which would then make y = 5.5. But that's wrong. What else can possibly be done?
