if the measure of the angles of a traingle are represented by 2x, 3x15, and 7x+15, the traingle is
1 an isosceles triangle
2 a right triangle
3 an acute triangle
4 an equilateral triangle

The sum of the measures of the three interior angles of a triangle is 180 degrees. So:
2x + 3x  15 + 7x + 15 = 180
12x = 180
x = 15
So the measures of the angles are 30, 30, and 120.
That should be enough for you to answer the question.
