Use a compass and straightedge to construct a dilation of quadrilateral

ABCD with the given center and scale factor k.

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

but which class are u may know that first
