NEED HELP Rectangle ABCD was dilated to create rectangle A'B'C'D'. Calculate the length of C'C. Round to
the nearest hundredth.

18

Step-by-step explanation:

first figure out how much it was dilated by. 4.4 times X equals 15.4. So 15.4 divided by 4.4 gives us X, which is 3.5.

multiply 7.2 by 3.5, and get 25.2, then subtract 7.2 to get C'C. Its 18.

C'C = 18

Step-by-step explanation:

A'B' = 7.2

B'C' = 4.4

BC = 15.4

4.4 * X = 15.4

4.4 * 3.5 = 15.4

3.5 is the dilation

7.2 * 3.5 = 25.2

AB = 25.2

25.2 - 7.2 = 18

C'C = 18

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
