I figured it out......i dont understand why no one has helped me yet in the past week

physics what am i doing wrong?
Three masses are arranged in the (x, y) plane. 3kg (0,0) 7kg (10,0) 6kg (0,3) What is the magnitude of the resulting force on the 3 kg mass at the origin? The value of the universal gravitational constant is 6.6726 × 10^−11 N · m^2/kg^2. Answer in units of N...
