Question

current skill $
what is the value of x?

Explanation:

Step1: Identify same-side interior angles

Same-side interior angles are supplementary, so $2x + (2x + 20) = 180$.

Step2: Simplify the equation

Combine like terms: $4x + 20 = 180$.

Step3: Isolate the variable term

Subtract 20 from both sides: $4x = 180 - 20$
$4x = 160$

Step4: Solve for x

Divide both sides by 4: $x = \frac{160}{4}$

Answer:

$x = 40$
