You would start off by setting up the equation as follows:
tan20=50/x (You would use tan because of the chief, SOHCAHTOA tan is opposite over adjacent.
multiply by x on both sides leaving you with
xtan20=50
Divide by tan 20.
Your answer would be 137.37 meters
tan20=50/x
xtan20=50
50/tan20
137.37 meters
tan20=50/x
xtan20=50
50/tan20
137.37 meters
