Question

Using the Pythagorean Theorem, how do you find the length of side a given b = 11 , c = 17?

Answer 1

`a = 2sqrt(42) ~~ 12.9614`

Explanation:

the Pythagorean Theorem formula is
`a^2 + b^2 = c^2`

given `b = 11, c = 17`

`a^2 + (11)^2 = (17)^2`
`a^2 + 121 = 289`
`a^2 = 289 - 121 = 168`
`sqrt(a^2) = sqrt(168)`
`a = 2sqrt(42) ~~ 12.9614`
