It’s a crazy sock day at school. You have four brown socks, 7 blue socks, and 8 black socks. What is the probability that you will choose a black sock, replace it and then choose a blue sock?

no, because the sides are not congruent

i dont know

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
