Chapter 1, Problem 1.36SP
Two observation towers A and B are located 300 ft apart, as shown. An object on the ground between the towers is observed at point C, and the observer on tower A notes that the angle CAB is 68° 10’. At the same time, the observer on tower B notes that the angle CBA is 72° 30’. Assuming a horizontal surface and towers of equal height, how far is the object from each tower and how high are the towers?
