No

Explanation:

For something to be a right triangle, you need to use the Pythagorean Theorem (#a^2+b^2=c^2#). In this case, it will be #x^2+z^2=y^2#, since y is the longest side.

Substituting x=15, y=19, and z=16, you get #15^2+16^2=19^2#.

Solve both sides. 481=361. This statement is false; therefore, 15-16-19 is not a right triangle.
