Answer 1

you must use pythagorean's theorem

a^2 + b^2 = c^2 where "c" is always the longest side (hypotenuse)

Answer 2

yup, use it :)

Answer 3

17^2 + 15^2 = c^2

solve c

Answer 4

Ok, I worked it out and got to 514=c^2,
Where do I go from there?

Answer 5

take sqrt both sides

Answer 6

514 = c^2

\(\sqrt{514} = c\)
