Answer:

The variable in the expression is 'c'.

Step-by-step explanation:

A variable is a letter that we use to represent a number that changes. "c" is the only letter in the expression, so its the variable.

We use variables when we do not know what the number should be, or when it's unknown.

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

<h3>What is the triangle?</h3>

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;

\rm tanx^0= \rm \frac{y}{115} \\\\ tan 42''=\frac{y}{115}

The calculations will determine the lighthouse's height as;

\rm tan 42''=\frac{y}{115}

Hence the best choice is A.
