Answer :
Answer:
17 ft
Step-by-step explanation:
Use pythagorean theorem:
[tex]{a}^{2} + {b}^{2} = {c}^{2} [/tex]
The rectangular storage unit is split into 2 right triangles since it is 17 feet diagonally. So, 17 feet is the hypotenuse of the right triangle.
[tex] {8}^{2} + {x}^{2} ={17}^{2} [/tex]
Once you solve everything you will find that x^2 = 225, so x = 15 ft. That is the length of the storage unit.
