Question

A ghost on a 135 feet cliff perpendicular (at 90 degrees) to the ground looks down at an angle of 16 degrees and sees a

Answer 1

To solve this problem you must apply the proccedure shown below:

1. You can make the diagram attached, where the ghost is identified as G and the the werewolf as W. The distance between both of them is y and the distance of the werewolf from the base of the cliff is x.

2. Let's calculate y:

$Cos(16)=\frac{135}{y}$

$y=\frac{135}{Cos(16)}$

$y=140.44$ ft

3. Now, let's calculate x:

$Tan(16)=\frac{x}{135}$

$x=(135)(Tan(16))$

$x=38.71$ ft

The answer are:

• The ghost is 140.44 feet from the werewolf.
• The werewolf is 38.71 feet from the base of the cliff.
