Braylen stands on an 8-foot platform and sights a swimmer at an angle of depression of 5°. If Braylen is 6 feet tall, how far away is the swimmer from the base of the platform to the nearest foot?

Respuesta :

The swimmer is 160 feet from the base of the platform

The diagram representing this illustration is shown below

Braylen's height = 6 feet

The platform's height = 8 feet

Total height = 8 + 6

Total height = 14 feet

Angle of depression, θ = 5°

Let the distance between the swimmer and the base of the platform be x

The value of x is calculated using the trigonometric identity below

[tex]tan \theta = \frac{Opposite}{Adjacent} \\\\tan 5 = \frac{14}{x} \\\\\\0.0875 = \frac{14}{x} \\\\\\0.0875x = 14\\\\\\x = \frac{14}{0.0875} \\\\\\x = 160[/tex]

The swimmer is 160 feet from the base of the platform
