A 10-meter telephone pole casts a 17-meter shadow directly down a slope when the angle of elevation of the sun is 42o (see figure). Find θ, the angle of elevation of the ground (to the nearest tenth of a degree). (A calculator is needed for this problem
+36916 Here is a quick sketch of my answer:
error 14 m should be 17m
sin 138/17 = sin y /11.106 y = 25.92 degrees
slope = 42 - 25.92 = 16.1 degree slope
