The tangent of u is the height of the zipline triangle divided by thebase: tan u = ry>rx. We know both u and the base of the triangle,rx, and hence we can rearrange this relationship to find the heightry. Similarly, the length of the zipline can be obtained by solvingcos u = rx>r for r

Question

The tangent of u is the height of the zipline triangle divided by the
base: tan u = ry>rx. We know both u and the base of the triangle,
rx, and hence we can rearrange this relationship to find the height
ry. Similarly, the length of the zipline can be obtained by solving
cos u = rx>r for r
