A roller coaster moves 200 ft horizontally, then rises 135 ft at an angle of 30.0° above the horizontal. Next, it travels 135 ft at an angle of 40.0° below the horizontal. Use graphical techniques to find the roller coaster's displacement from its starting point at the end of this movement.

magnitude ft
direction ° (measured counterclockwise from the +x axis)

the horizontal displacement is
200+135*cos(30)+135*cos(40)

Vertical is
0+135*sin(30)-135*sin(40)
