Answer 2

No, the sides of a triangle cannot have the lengths 2, 5, and 5.

Explanation:

Using the right triangle formula, aka. the Pythagorean Theorem, which is
`a^(2)+b^(2)=c^(2)` we need to substitute the sides given with the variables.

`2^(2) +5^(2) =5^(2)`

Simply to
`4+25=25`.

Add 4 to 25.
