    If they are supplementary, then they have to be equal to..?

    Since these two measurements are supplementary, set both of them equal to 180

    Therefore, (6x - 4) + (8x - 12) = 180

    so I can just add them together and use algebra to find x? 14x-16=180 14x=164 x = 11.7142857142857

    Now, x is equal to 11.71. You have to plug it back into the given measurements as "x" to get their degrees

    it's 14x-16=180 14x = 196 x = 14

    Ah there we go. My mistake I did not point that out! =P Now, you can plug them into the original measurements to conclude to your final answer ;)

    so one angle is 80° and the other is 100°
