if the measure of the angles of a traingle are represented by 2x, 3x-15, 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.
