Jack delivered 90 circulars in 20 minutes. At this rate, how long will it take him to deliver 135 circulars?

The coordinates of vortex a’ are (8,4) (-4,2) (4,-,4) the coordinates of vortex b’ are (6,6)(12,-,12)(12,12) the coordinates of vortex c’ are(-2,,12)(4,12)(12,-4)

If two parallel lines are cut by a transversal, interior angles on the same side of the transversal are supplementary. a. always b. sometimes c. never

Measure a and b and find their sum. how are the angles related?
