An equilateral triangle 10.0 m on a side has a 1.00-kg mass at one corner, a 2.00-kg mass at another corner, and a 3.00-kg mass at the third corner.

Find the magnitude of the net force acting on the 1.00 kg- mass.

Find the direction of the net force acting on the 1.00-kg mass.

theta= degrees below horizontal to the left.
