Question

What is the unknown side of the triangle?

Answer 1

use the Pythagorean Theorem.
`a^(2)` +
`b^(2)` =
`c^(2)`

so it would,
`12^(2)` +
`16^(2)` =
`c^(2)`

so what you do now is simplify
`12^(2) + 16^(2)`, which will equal 400.

so now you have
`c^(2) =400`, so then you square root 400 to get rid of the squared.


`\sqrt{ c^(2) } = √(400)`



`√(400) = 20`

so your unknown side is 20 :P
