Answer: 34.64 m
Step-by-step explanation:
Given: A boat is 60 m from the base of a lighthouse.
The angle of depression between the lighthouse and the boat is 37°.
By using trigonometric ratios :

here x= 37°, side opposite to x = height of lighthouse (h) , side adjacent to x = 60 m

Hence, the lighthouse is 34.64 m tall.
Answer:
<h2>25</h2>
Step-by-step explanation:
So there is this property,
Sum of two angle of triangle = exterior angle
So based on this we can form an algebraic equation (NOTE: this is an equilateral triangle so all the sides are 60°)

So it's option B.
