Question

1. - / 1 points given that $ell_1parallelell_2$, find $x$. $x =$

Explanation:

Step1: Use angle - relationship of parallel lines

Since $\ell_1\parallel\ell_2$, the sum of the same - side interior angles is $180^{\circ}$. So, $6x + 4x=180$.

Step2: Solve the equation

Combine like terms: $10x = 180$. Then divide both sides by 10: $x=\frac{180}{10}=18$.

Answer:

$18$
