Add 2 1 over 3 + 4 5 over 8 Write your answer as a mixed number.

i belive those are the ones that are under 90 degreese.

what's the question?

step-by-step explanation:

there is no question.

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)
