Name the pair of complementary angles and pair of supplementary angles

Complementary angles are those angles whose sum is 90

Supplementary angles are those angles whose sum is 180

<QTS= 150

<RTS=60

<VWU= 30

Hence <QTS + <VWU = 150+30= 180 are supplementary angles

and <RTS + <VWU= 60+30 = 90 are complementary angles

the one that has a slope of 1/2 and is positive.
