I need the value of X

X=13°

Step-by-step explanation:

angle 6 = 69° because they are vertically opposite angles and angle 6 and 5x+4 are equal to each other because they are corresponding angles because given 2 lines are parallel given in question's diagram and then

=> 5x+4 = 69°

=> 5x = 69°-4

=> 5x = 65°

=> x= 65°/5

=> x = 13°

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
