Triangle abc is transformed with the center of dilation at the origin. pre-image: △abc with vertices a(2, 5), b(6, 10), c(9, −1) image: △a′b′c′ with vertices a′(0.5, 1.25), b′(1.5, 2.5), c′(2.25, −0.25) what is the scale factor of the dilation that maps the pre-image to the image? enter your answer in the box.

1/4

Step-by-step explanation:

you see, 2/4=0.5, 5/4=1.25, 6/4=1.5, basically,all the numbers are divided by four, so your scale of dilation is 1/4.

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
