Answer:

Step-by-step explanation:
Ok, so we start off with 
Then, we subtract 2 from both sides so that becomes: 
After that, we simplify to get: 
Finally, the solution becomes: 
Answer:

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
It’s actually a. Multiply by the square root of 2
You can verify using the Pythagorean Theorem.
