Which line represents a direct variation function?

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

i think it is c, not positive though

step-by-step explanation:

c. (3,2,6) is the answer.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
