Find the length of the segment with the given endpoints.

(17.1, 3), (21.4, 3)

4.3

Step-by-step explanation:

Because the y-coordinate stays the same, only look at the x-axis. Subtract 17.1 - 21.4 to get your length

were is the equation

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
