Choose the most accurate relationship between ∠1 and ∠2. a. adjacent b. linear pair c. supplementary d. vertical

Option A

Adjacent

Step-by-step explanation:

we know that

Two angles are adjacent when they have a common side and a common vertex

In this problem

m∠1 and m∠2 has a common side and a common vertex

so

m∠1 and m∠2  are adjacent angles

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
