Charles owed $390 to his friend. on the first day charles paid his friend $12. each following week the amount charles paid his friend increased by the same amount. after 10 payments, charles had paid back the full amount. by how much did each payment increase?

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
