What is the length of line cg with bar on top when AG = 15 in., AD = 9 in., and DC = 10 in.? Round your answer to the nearest tenth of an inch. This is not multiple choice. I need help. This is my only question please and thank you.

Answer: The length of line CG with bar on top is 20.1 in.
First, calculate the hypotenuse of Triangle ADG. Measurements for lines AD and AG are given so solve for DG.

DG = 17.49 in
Lastly, calculate the third side of Triangle DGC. DC and DG are now known, solve for CG.

CG = 20.1 in

Answer I got 6.6. If there was a attached photo, the answer would change.

Its a rectangular prism that has a unknown length. In order to solve this, you have to solve another triangle. Plus in the photo (which is not included) , the hypotenuse is already provided when you solve the first triangle so the line cg is what is asking for so 6.6² + other line² = the given hypotenuse. I did this equation a bitago so I don't want to rethink about the whole thing again.
