Answer 1

14.4 inches

Explanation:

Using the Pythagorean Theorem (
`a^2+b^2=c^2\\`)

`12^2+8^2=c^2\\144+64=c^2\\208=c^2\\c=√(208) = 14.4`

Hope this helps you out!

Answer 2

The first one is a triangle because: The two smaller sides of a triangle must add up to be larger than the longest side.
14 + 12 = 26 > 19
