    and the other says, "Thanks, you look quite good yourself" ? Is that what you mean by they compliment each other?

    that means they add up to 90 degrees, correct?

    A : B = 1 : 9, right?

    and A+B = 90. Are you with me?

    good. so you have two equations A + B = 90 and A/B = 1/9

    A / B = 1 / 9 => A = 9B

    substitute A in the other equation and solve for B
