Question

If the distance from the boat to the lighthouse is 120 meters and the angle of elevation is 40°, which of the following equations will find the height of the lighthouse?

Answer 1

Answer:

the equation of the height= tan 40 = y/ 120

Step-by-step explanation:

since the distance between the boat and the light house is 120°

: using trigonometry

tan theta = opp/adj

therefore it is y/120°

Answer 2

= tan 40 = y/ 120
