Height of the lighthouse = 250 feet
Distance of the ship from the shore = 2.5 miles
We already know that
1 mile = 5280 feet
Then
2.5 miles = 5280 * 2.5
= 13200 feet
Now, to find the angle of depression, we can use the formula
θ = tan−1 (13200/250)
= 1.50 degrees
I hope that this is the answer that you were looking for and the answer has come to your desired help.
