Hey guys I'm lost with this word problem. A roller coaster moves 85m horizontally, then travels 45m at an angel of 30.0° above the horizontal. What is its displacement from its starting point? I started out by drawing a 85m line. But now I'm confused because I have to set a 30 degree angle. Would I draw a line to the northeast or northwest? That's all the need I'll need for now. Thanks guys!
