​

Answer 1

`c=√(130)\\`

Explanation:

When we solve for this we should always remember this formula
`a^2+b^2=c^2` and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.

`a^2+b^2=c^2\\7^2+9^2=c^2\\49+81=c^2\\130=c^2\\√(c^2)=√(130)\\c=√(130)`

So c would equal whatever the square root of 130 is.
