Answer:
Option B, x = 20
Step-by-step explanation:
<u>Step 1: Make an equation</u>
The values of 65 degrees and (3x + 5) are equal.
65 = 3x + 5
<u>Step 2: Subtract 5 from both sides</u>
65 - 5 = 3x + 5 - 5
60 = 3x
<u>Step 3: Divide both sides by 3</u>
60 / 3 = 3x / 3
<em>20 = x</em>

Answer: 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!
