    In a triangle the sum of the angles is 180 degrees. If Angle A is four times Angle B and Angle C is 27 degrees more than three times Angle A. Find the measures of the three angles to the nearest degree.

    let angle B be x then angle A will be 4x and angle C will be 3*4x+27 = 12x + 27

    sum of the angles is 180 degrees

    4x + x + 12x + 27 = 180

    17x = 180 - 27

    17x = 153

    x = 9

    Angle A = 4x = 4*9 = 36 degrees

    Angle B = x = 9 degrees

    Angle C = 12x + 27 = 12*9 + 27 = 135 degrees
