What is the length of the unknown leg of the right triangle for 7 feet and 9 feet? Plz help, I'll do anything.

Answer 1

Answer:

$\sqrt{130}$

Step-by-step explanation:

If you are trying to find the hypotenuse, then you want to use the equation a^2 + b^2= c^2

1. 7^2 + 9^2=c^2

2. 49+81=c^2

3. c^2=130

4. Square root both sides
