Question

A lifeguard is sitting in an observation chair at a pool. The lifeguard's eye level is 6.2. feet fromground. The chair is 15.4 feet from a swimmer. Calculate the measure if an angle forms when thelifeguard looks down at the swimmer.

Answer 1

We can represent this situation with a triangle, as shown below:

We need to calculate the angle that forms between the line of sight of the Life Guard and the swimmer. For that, we will have to use the tangent relation.
