Question

given ( m parallel n ), find the value of ( x ).

Explanation:

Step1: Identify supplementary angle pair

$x^\circ$ and $86^\circ$ are same-side interior angles, so they are supplementary.

Step2: Set up supplementary angle equation

$x + 86 = 180$

Step3: Solve for x

$x = 180 - 86$

Answer:

$94$
