Question

From the top of the Eiffel tower, which is 984 feet tall, you look down and see your friend at a 60°

angle of depression. How far is your friend from the foot of the tower?

Answer 1

The answer is 492 feet.

If we picture the scenario as a right triangle, using trigonometric ratios, this problem can be solved.

cos 60° = x / 984

1/2 = x/984

x = 984/2

x = 492 feet
