Skydiver jumps out of a plane she falls down word and very fast P. When she Open Sarah parachute she slows down. What force pulls the skydiver to the ground?

There are two forces acting on a parachute with a parachutist: the force of gravity and the air resistance. The force pulling the skydiver to the ground would be Wright force

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way
