The question is below

see explanation

Step-by-step explanation:

b = 79° ← corresponding angles are congruent

c = 83° ← vertical angles are congruent

a and b and c and d are same side interior angles and are supplementary, thus

a = 180° - b = 180° - 79° = 101°

d = 180° - c = 180° - 83° = 97°

Thus

a = 101°, b = 79°, c = 83°, d = 97°

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

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
