Question

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

Explanation:

Step1: Find supplementary angle

The angle adjacent to $113^\circ$ on line $l$ is supplementary:
$180^\circ - 113^\circ = 67^\circ$

Step2: Use triangle angle sum

The three angles (67°, 80°, $x$°) form a triangle, so their sum is $180^\circ$:
$x = 180^\circ - 67^\circ - 80^\circ$

Step3: Calculate final value

$x = 33$

Answer:

$33$
