Let width = x, Therefore the length must equal 2x
Therefore insert these values on the sides of a rectangle.
Add: 2x + 2x + x + x = 18
Therefore 6x = 18
x = 3

I think its is 4/5 but not positive
1 is the 3rd option down
2 is the second option down
Answer:
x=80
Step-by-step explanation:
The angle of a line is 180*.
The equation would be (x+20)+x=180
Subtract 20 from both sides: 2x=160
Divide by 2: x=80
That's your answer!
I hope this helps!
