If the measures,in degrees, of the three angles of a triangle are x, x+10, and 2x-6, the triangle must be:
A.right,B.equilateral,C.Scalene, D.Isosceles

  • Geometry -

    Note first that
    x + x + 10 + 2x-6 = 180
    4x = 176
    So the three triangle sides are
    x = 44
    x + 10 = 54, and
    2x -6 = 82

    The triangle is scalene.
