At the same time of day a cable pole and a yard stick cast shadows of 20 ft. and 4 ft. persfectively as shown in the diargram below. if the angle of elevation of the sun is the same for both the cable pole and the yard stick determine the height od the cable pole.

The ratios of the lengths of the pole and yarstick are the same in relation to their shadows. In other words, the ratio of length/shadow of one equals the ratio of length/shadow of the other. Use X for the height of the pole, and plug in the other three values. Make sure you are using the same size units for all three.

I hope this helps. Thanks for asking.
