3 an acute triangle

4 an equilateral triangle

**RickP**, Thursday, May 7, 2009 at 10:16pmThe 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.
