Answer 1

Equations A will find the height of the lighthouse. Option A is correct.

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

(d)distance from the boat to the lighthouse =115 meters

Θ is the angle of elevation = 42"

h is the height

Apply the tangent formula in the obtained triangle;

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

The equations will find the height of the lighthouse is;

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

Hence, option A is correct.
