A 100 m cable is stretched from the ground to the top of a pole. If the angle of the cable with the ground is 10 degrees, how high is the pole?
A. 17.4 m
B. 90 m
C. 98.5 m
D. 110 m
Imagine a right angle triangle with the diagonal side being 100m long. Since the angle between the ground and cable is 10 degrees, sin 10 = pole/cable.
