1) Bob wants to measure the building and decides to use a mirror to do so. He stands away from the building and looks into the mirror on the ground, moving away or closer to the mirror until he can see the top of the building in the mirror. His friend measures the distance between the building and the mirror, and the mirror and Bob. They draw the following picture to demonstrate the distances. Solve for the height of the building:
2) A man who is 6 feet tall stands in front of a flagpole. His shadow is 10 feet long and the distance from the flagpole to the tip of his shadow is 85 ft. How tall is the flagpole?

You are playing tennis are are ready to serve the ball. You hit the ball at a height of \(8’\) . You are standing on the baseline, \(39’\) from the \(3.5’\) net. Where will the ball land on the other side of the net?
Did you get \(50’\)and \(51’\), \(30.3’\) and \(77’\)?
