HELP If the distance from the boat to the lighthouse is 115 meters and the angle of elevation is 42 which of the following equations will find the height of the class=

Respuesta :

Equations A may be used to determine the lighthouse's height. The best choice is A.

What is the triangle?

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

Given;

(d) 115 meters separate the boat from the lighthouse.

42" is the angle of elevation.

Height is h

Apply the tangent formula in the obtained triangle;

[tex]\rm tanx^0= \rm \frac{y}{115} \\\\ tan 42''=\frac{y}{115}[/tex]

The calculations will determine the lighthouse's height as;

[tex]\rm tan 42''=\frac{y}{115}[/tex]

Hence the best choice is A.
