8. What is the value of x?

16

Step-by-step explanation:

The midpoint theorem says that if a line bisects the two sides of the triangle , it is parallel to the third side and half of it

Thus the x = 1/2 × 32 = 16

sine

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
