Trent is fishing from a pier: The tip of his fishing rod is 53 3/4 feet above the surface of the water. The hook on the end of the fishing line is directly below the tip of the fishing rod 12 2/3 feet below the surface of the water. Trent lets his hook drop another 10 inches. What is the distance, in feet, between the tip of the fishing rod and the hook?

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
