Answer and Step-by-step explanation:
To solve for x, we add together the angles, and equal it to 180.
This is because the angles shown are same side interior angles, and add up to 180 degrees.
x + 3x + 40 = 180
<u>Subtract 40 and combine like terms.</u>
4x = 140
<u>Divide 4 from both sides of the equation.</u>
x =
<u>The value of x is 35.</u>
