Answer 1

imagine drawing a line between the top of the lighthouse and the boat
the angle of that line, drawn down from the horizontal, is the angle of depression

because we have two parallel lines (top horizontal and bottom horizontal) cut by a transversal, the angle of depression and the angle of elevation are both equal (both marked by theta)

now, looking at the lower theta, you have the opposite and adjacent sides

so tan(theta) = opposite/adjacent = 275/1324 solve for theta

Answer 2

it's 11.7 degrees?

Answer 3

good
