Question

1. - / 1 points given that $ell_1parallelell_2$ and $y = 42^{circ}$, find $x$. $x= ^{circ}$

Explanation:

Step1: Use property of parallel lines

When two parallel lines $\ell_1$ and $\ell_2$ are cut by a transversal, the corresponding angles are equal. So, $x + y=2x$.

Step2: Solve for $x$

Subtract $x$ from both sides of the equation $x + y=2x$. We get $y = 2x - x$, which simplifies to $x=y$.

Answer:

$42$
