Lines m and n are parallel. find the value of x.
A. 15
B. 20
C. 65
D. 115

Option B, x = 20

Step-by-step explanation:

Step 1:  Make an equation

The values of 65 degrees and (3x + 5) are equal.

65 = 3x + 5

Step 2:  Subtract 5 from both sides

65 - 5 = 3x + 5 - 5

60 = 3x

Step 3:  Divide both sides by 3

60 / 3 = 3x / 3

20 = x

 Option B, x = 20

The angle 65° is the same as the angle (3x + 5)° because their parallel.

We can write this as (3x + 5) = 65

Now, solve for x.

3x + 5 = 65

3x + 5 - 5 = 65 - 5

3x = 60

3x/3 = 60/3

x = 20 (Option B)

Best of Luck!
