Answer 7

you can use pythagorean theorym to solve this.
so set up the problem like this:

a^2 + b^2 = c^2
or
17^2 + 9^2 = c^2
or
289 + 81 = c^2
or
370 = c^2

to solve, you square root both sides, so it should look like this:

\[c = \sqrt{370}\]

in other words, the square root of 370 is your answer
