You can put this solution on YOUR website! Let x = original angle
.
Let y=complement,,,,,x+y=90,,,,y=90-x
.
Let z=supplement,,,,x+z=180,,,,z=180-x
.
given,,,,z=20 +2y,,,,,,,,,,substitute
.
(180-x) =20 +2(90-x) = 20 +180 -2x
.
x=20,,,,answer,,,,,y=70,,,,,,z=160,,,,all degrees
.
.
check,,,,,160 = 20 +2(70),,,,,ok
