Answer:

The anchor is 12 feet far from the point directly below the boat.

Explanation:

Given that:

Length of rope connecting the dive boat to an anchor = 13 feet

Depth of water = 5 feet

Here,

The rope connecting the dive boat to the anchor will serve as hypotenuse of a right angle triangle, depth of water will be the height of triangle and distance from anchor to point directly below the boat will be base of triangle.

Using Pythagorean theorem;


a^2+b^2=c^2

a = 5 , c = 13


(5)^2+b^2=(13)^2\\25+b^2=169\\b^2=169-25\\b^2=144

Taking square root on both sides


√(b^2) =√(144)\\b=12

Hence,

The anchor is 12 feet far from the point directly below the boat.
