Question 286720: the measures of the angles of the angles of a triangle are represented by 2x,3x-15, and 7x+15,the triangle is
(A) an isosceles triangle
(B) a right triangle
(C) an acute triangle
(D) an equiangular triangle

angles in a triangle add up to 180
2x+3x-15+7x+15=180
12x=180
x=180/12=6*2*15/12=15
x=15
2x=30
3x-15=30
7x+15=120
(A)an isosceles triangle
