Question

I'm not sure how to find "s". I've tried using a^2+b^2=c^2 but that doesn't match any of the answer choices. If you could show work that'd be great!

Answer 1

The line segments labeled 8, 9, and
`s` form a right triangle, so Pythagoras' theorem holds:

`8^2+9^2=s^2\implies s=√(8^2+9^2)=√(64+81)=√(145)`

None of the provided choices are correct...
