in the figure below, $l \\parallel m$. find $x$.\n$x = \\square$
in the figure below, $l \\parallel m$. find $x$.\n$x = \\square$
Answer
Explanation:
Step1: Find adjacent angle on line m
The supplementary angle to $132^\circ$ is $180^\circ - 132^\circ = 48^\circ$.
Step2: Use alternate interior angles
The $39^\circ$ angle on line $l$ has an alternate interior angle of $39^\circ$ on line $m$.
Step3: Apply triangle angle sum
The sum of angles in a triangle is $180^\circ$. So $x = 180^\circ - 39^\circ - 48^\circ$. $x = 93^\circ$
Answer:
$93$
