Aboat is 20 ft away from a point perpendicular to the shoreline. a person stands at a point down the shoreline so that a 60° angle is formed between the closest point to the boat, the person, and the boat. how far is the person from the boat? draw a picture showing the right triangle. round your answer to the nearest tenth of a foot.

Distance of the person from the boat is 23.1 feet.

Step-by-step explanation:

We have,

The distance of the boat from the shoreline = 20 feet.

Angle between the boat and the person = 60°

So, we get the right triangle as shown in the figure.

As, in a right triangle, the angles and sides can be written in trigonometric form.

Thus,

i.e.

i.e.

i.e.

i.e. x = 23.1 feet.

Thus, the distance of the person from the boat is 23.1 feet.

0 is its x and y coordinate

the answer is  

a.

28 ft2
