## Homework Statement

Find the normal force acting on a mass of 5kg on an incline plane of 30 degrees.

## Homework Equations

Fn = mgsin30 or mgcos30 ?

## The Attempt at a Solution

I'm not sure if I use sin or cos when finding the normal force on an incline. I have trouble visualizing the angle perpendicular to the plane and moving the angles around.
