Aboat is 15 ft away from a point perpendicular to the shoreline. a person stands at a point down the shoreline
so that a 65° angle is formed between the closest point to the boat, the person, and the boat. how far is the
person from the boat? round your answer to the nearest tenth of a foot.

0 is its x and y coordinate

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
