Question

The measure,in degrees,of the three angles of a triangle are given by 2x + 1,3x - 3, and 9x.Whar is the measure of the smallest angle

1 Answer

  • (2x+1)+(3x-3)+9x = 180

    14x-2 = 180

    14x = 182

    x = 13


    Plugging back in, your angles are 27 degrees, 36 degrees, and 117 degrees, respectively.  So the 2x+1 angle is the smallest.
