The answer to the question above

x=20

Step-by-step explanation:

so we just mark ADB as 45 and BDC as 50 and now we can find B and C by doing 180-50=130/2 so B=65 and C=65 now we have 2 angles so we can find x. D is 95 bc we add 45 and 50 and C is 65 like i wrote there so we add 95+65 and get 160 and we subtract 160 from 180 to get x=20

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
