Kevin has created a triangle that includes angles measuring 30 degrees and 40 degrees.

With two angles specified, we should determine the measure of the third angle.

According to the angle sum property, which indicates that "the total of all triangle angles must equal 180 degrees".

Let’s denote the third angle as 'x'

Hence, $30^{\circ}+40^{\circ}+ x = 180^{\circ}$

$x = 110^{\circ}$

This results in triangle angles of 30 degrees, 40 degrees, and 110 degrees, with side lengths of 5 cm, 7 cm, and 8 cm.

Based on the information provided:

"A triangle is classified as scalene when all three sides are unequal (and consequently, all three angles are also unique)."

Thus, Kevin has drawn a scalene triangle since the angles vary in measures and all sides differ in length.

He created a scalene triangle.
A scalene triangle has sides and angles that do not measure alike.
