Homework Statement

A Nordic jumper goes off a ski jump at an angle of 10.0 degrees below the horizontal, traveling 108 meters horizontally and 55.0 meters vertically before landing. (a) ignoring friction and aerodynamic effects, calculate the speed needed by the skier on leaving the ramp.

I don't know where to start :(

start by drawing a diagram. Then can you write the horizontal and vertical equations?
