You can put this solution on YOUR website! if the first angle is x, then the complement is 5x+9.
complement means that both angles added together equals 90
so the equation is x+5x+9=90
combine like terms 6x+9=90
then subtract 9 on both sides 6x=81
divide 6 x=13.5
this is the first angle.
the second angle is 5x+9, so substitute 13.5 for x
5(13.5)+9=76.5
check: 13.5+76.5=90
so the first angle is 13.5 and it's complement is 76.5.
