The sum of the angles in a triangle is 180.
Since the ratio of the angles is 2:3:5 their measurements are 2x, 3x, and 5x.
When you add them together you will get 180. So...
2x+3x+5x=180
10x+180
x=18
Since x=18 the measure of the angles are
2x=36
3x=54
5x=90
Since one of the angles is 90 we know that the triangle is a RIGHT triangle.
