Rewrite each number as an improper fraction to multiply

2 1/4 = 9/4

3 1/5 = 16/5

Now multiply:

9/4 x 16/5 = (9 x 16) / (4 x 5) = 144/20

Now rewrite as a proper fraction:

144/20 = 7 4/20 = 7 1/5

The answer is 7 1/5

The angle of depression from the top of a cruise ship to the top of a sailboat is 22. Sitting above water, the cruise ship is 23

dusya [7]

Answer:

The distance between the cruise ship and the sail boat is 517 feet.

Step-by-step explanation:

The cruise ship is 236 feet tall, and the sailboat is 236 tall; this means the distance between the top of the cruise ship and the top of the sail boat is

236 feet - 27 feet = 209 feet.

We also know that the angel of depression from the top of the cruise ship to the bottom of the cruise ship is 22°. This forms a right triangle as shown in the figure attached.

Now from trigonometry we get:

$tan \: \theta = \dfrac{209}{d}$
