## Homework Statement

Well I am trying to get help on weight compent. It is a box sliding on an inclined surface with angle 30 degrees.

## Homework Equations

w= mg

## The Attempt at a Solution

I am trying to find the components for weight force acting on the box. Book says w=mgcos(30) is when its perpendicular to surface, and w= mgsin(30) when its parallel to surface. Can someone explain how to do this?

Thanks
