In the diagram below, the angle of depression from the top of the lighthouse to a speed boat is 27 degrees.  The base of the lighthouse is 33 ft away from the boat.   Determine the height of the lighthouse, to the nearest tenth of a foot.​

In this lesson, you will learn how to create moods in photographs. To get started, try to remember the last time you saw a photograph that caused a great emotional response.

Why did you react to this photograph in the way you did? Was your reaction positive or negative, and what made it that way? Do you think you would not have reacted as strongly to a photograph of the same subject if it had been shot differently?

Write an answer in three to five sentences that describes this photograph and your reaction to it. In your response, you should thoroughly explain every statement you make.

Step-by-step explanation:

Step-by-step explanation:

The angle of depression is always measured from the horizontal.

A triangle is formed by the lighthouse, the ground and the boat. The angle of depression is not in the triangle, but it is equal to the angle of elevation at the boat. (Alternate angles on parallel lines)

The angle at the top of the lighthouse, inside the triangle is:

90°−27°

=63°

The distance to the boat is the side opposite the angle of

63°

while the height of the lighthouse is the adjacent side.

=tan 63°

210=tan 63°

distance=210×tan 63°=412 feet

Step-by-step explanation:

4 is equal to 100

2 is half of 4

100 ÷ 2 = 50
