imagine that this is a right triangle...the hypotenuse will become your slope (200m) and theta will be the inclination (9 degs) ...now you're looking for the side adjacent your angle..which is the horizontal distance covered. so to get the adjacent side you use cosine  (theta) = Adjacent/Hypotenuse

cos(9) = A/220

A = 220 cos(9) 

input that in the calculator to get your answer :)
