What is the cosine ratio of angle A? In other words, what is cos(A) ? A: 5/13
B: 5/12
C: 12/13
D: 12/5

b. x- 48 =120

step-by-step explanation:

the answer is 8/21

hope this

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)
