In circle M, segment AB is tangent to the circle at point C. AB has endpoints such that AM BM  ,
AC  9 and BC  4 . What is the length of the radius of circle M. Show how you arrived at your answer.

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)

you would 18 *0.25 = 4.5
