## Homework Statement

Three forces at on an object. A 35-N force acts an angle of 20^o relative to a 60-N force. A 40-N force acts at an angle of 75^o relative to the 60-N force on the opposite side of the 35-N force. Determine the equilibrium of the three forces.

Force 1 = 60 N

Force 2 = 35 N

Force 3 = 40 N

## Homework Equations

Sine law

Cosine law

## The Attempt at a Solution

I have no idea how to do this because my teacher only taught me about the forces dealing with two forces acting on an object.
