Question

Need help fast please thanks

Answer 1

c = 41 ft

Explanation:

To solve this problem, we can use the pythagorean theorem, which is defined by the formula
`a^2+b^2=c^2`. We are given both the lengths of the legs, so all we need to do is to plug them both in and solve for c:

`9^2+40^2 = c^2\\c^2 = 81 + 1600\\c^2 = 1681\\c = 41`

This is the first option.
