Sam needs to cross a cliff while hiking. He needs to know how wide the cliff is so he can cut a tree to use as a bridge.e He stands next to the cliff and targets a rock on the other side of the cliff. He approximated the angle formed by of his sight when looking at the rock and the edge of the cliff is about 50 degrees. He then walks about 10 feet and looks at the same rock again, approximating that the angle is now 70 degrees. Sam did not walk to the other side of the rock. He only walked 10 feet away from his initial position. Help sam find out the width of the cliff. Also find the equation for it.
