Jarvis needs to determine the distance across a lake. however, he can't measure this distance directly over the water. so, he set
up a situation where he could use the measurements of two similar triangles to find the distance across the lake.
he selects a point x such that xz is perpendicular to vz, where v is a point at the other end of the lake. he then picks a point y
on xz. from point y he finds point w on xv such that wy is parallel to vz
ifxy = 2,984 feet, wy = 1,492 feet, and xz = 8,952 feet, what is the length of vz, the distance across the lake?
