A 70.0 kg skier rides a 2860 m long lift to the top of a mountain. The lift makes an angle of 14.8° with the horizontal. What is the change in the skier's gravitational potential energy?(adsbygoogle = window.adsbygoogle || []).push({});

Would I use the equation: PE= (mg*final height) - (mg*initial height)? What do I do with the 14.8degrees? Please help. I'm stuck.
