Question

in the figure below, ( l parallel m ). find ( x ).

Explanation:

Step1: Use exterior angle property

When two parallel lines are cut by transversals, the sum of the two interior angles equals the exterior angle. So we set up the equation:
$50 + x = 101$

Step2: Solve for x

Isolate $x$ by subtracting 50 from both sides.
$x = 101 - 50$

Answer:

$51$
