    4.) The three angles of a triangle are x , ( x+30), (x-6)
    The sum of the angle of a triangle is 180.
    x + (x + 30) + (x-6) = 180
    x + x + 30 + x – 6 = 180
    3x + 30 – 6 = 180
    3x + 24 = 180
    3x = 180 – 24
    3x = 156
    x = 52 degree
    (x + 30) degree
    52 + 30 = 82 degree
    (x – 6) degree
    52 – 6 = 46 degree
