Question

Problem: A pole is being held up with a 10 meter rope. The cable is making a 42° of elevation from the ground to

the top of the pole. What is the distance from the base of the pole to the base of the rope ? Round your answer
to the nearest tenth of a meter.

Answer 1

x = 7.4

Explanation:

cos(42°) = x/10 or distance from bases / rope length

Using the calculator find the value of cos(42°):

cos(42°) = 0.74 = x/10

Find x using the value of cos(42°):

x/10 = 0.74

x = 7.4
