The bridge is built next to a tree in order to mount a support rope from
each end. The height of the tree is 18 feet from the bridge and 4 feet from
Sarah's side.
Part 2: Sarah solved for the shorter side of the rope (x) using the
Pythagorean Theorem and Julio needs your help finding the error in the
calculation. Circle the first incorrect step in the work below. Fix the error
and find the correct length of x. If needed, round to the nearest
hundredth.
