Jane and Jim working together can sort a crate of apples in 10 minutes. Jim and Joyce can do the same job together in 15 minutes. Joyce and Jane can do the same job together in 20 minutes. How long would it take Jim, working alone, to sort 7 crates of apples

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)
