Chapter 10.2, Problem 1P

Figure 10.46 9 depicts sun rays traveling toward 3 points on the earth’s surface, labeled A, B, and C. Assume that these sun rays are parallel to the plane of the page. Figure 10.46 Sun rays traveling to the earth

1. Use a protractor to determine the angle that the sun’s rays make with horizontal ground at points A, B, and C.
2. Suppose there are telephone poles of the same height at locations A, B, and C. Make drawings like the ones in Figure 10.47 on which the vertical lines represent telephone poles, and show on your drawings the different lengths of the shadows of these telephone poles, using the information from part (a).
