#### Answer

It can be a right triangle.

#### Work Step by Step

The Pythagorean Theorem states that for a right triangle, $a^{2} +b^{2} = c^{2}$. In order to figure out if these sides can be the sides of a right triangle, we plug them into the Pythagorean Theorem:
$16^{2} + 30^{2} = 34^{2} \\\\ 1156=1156$
This is true, so it can be a right triangle.
