# Three Forces: Equilibrium

## Homework Statement

Forces of 5N, 7N, and 8N are applied to an object, calculate the angle between the lines of action of the 5N and 7N forces.

## Homework Equations

Sin, cos, and tan relationships

## The Attempt at a Solution

I know that you have to use components, but I don't see how to do this without knowing at least one angle.
