Question

the length of a hypotenuse if one right angle is 7 and the other is 9 how do you find the length

Answer 1

Pythagorean theorem. a^2+b^2=c^2. let a=7, b=9, solve for c.
7^2+9^2=c^2
49+81=c^2
c^2=130
c=sqrt(130)

Answer 2

\[h^2 = a^2 + b^2\]
so
\[h^2 = 7^2 +9^2\]
\[h^2 = 49 + 81\]
\[h^2 = 130\]
\[h = \sqrt{130}\]
