Question

follow the steps below to find the value of x that makes a||b. 10x 8x + 30 a b set the alternate exterior angles equal to each other. ?x = x +

Explanation:

Step1: Apply angle - equality property

When two lines are parallel, alternate exterior angles are equal. So we set up the equation based on the given angles.
$10x=8x + 30$

Step2: Solve for x

Subtract $8x$ from both sides of the equation.
$10x-8x=8x + 30-8x$
$2x=30$
Then divide both sides by 2.
$x = 15$

Answer:

$10x=8x + 30$, $x = 15$
