Based on the diagram below, which statement could be used to prove ∠ 1 ≅ ∠ 2 ? A. Vertical angles are congruent. B. Supplementary angles are congruent. C. Complementary angles are congruent. D. Two angles that form a linear pair are congruent.

answer:

D.

Step-by-step explanation:

It makes most sense :

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

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
