    The port support for a window air conditioning unit forms a triangle and an exterior angle. The sides are (5x - 6) degreesand the other angle is 3x degrees and last angle is 90 degrees.

    The su, of the interior angles of the triangle is 180

    (5x - 6) + 3x + 90 = 180

    X = 12, so the angles are 54 and 36

    The exterior angle will also form a 180 degree with the interior

    Depending which exterior angle

    1.) 180 - 54 = 126

    2.) 180 - 36 = 144
