in the figure below, $l \\parallel m$. find $x$. \n$x = \\square$
Answer
Explanation:
Step1: Use alternate interior angles
The angle corresponding to $67^\circ$ on line $m$ is also $67^\circ$.
Step2: Sum angles in a straight line
Angles on a straight line add to $180^\circ$. So $x + 80^\circ + 67^\circ = 180^\circ$.
Step3: Solve for $x$
Calculate $x = 180^\circ - 80^\circ - 67^\circ$ $x = 33^\circ$
Answer:
$33$
