Right Triangles and trigonometry please help ASAP

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

1

step-by-step explanation:

it's the only multiple of both and the least

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
