Question

given ( m parallel n ), find the value of ( x ).
answer attempt 3 out of 3
( x = )\\( ^{circ} ) submit answer

Explanation:

Step1: Identify supplementary angle

The angle adjacent to $140^\circ$ on line $m$ is $180^\circ - 140^\circ = 40^\circ$.

Step2: Use corresponding angles property

Since $m \parallel n$, $x$ is equal to the $40^\circ$ angle (corresponding angles are congruent).

Answer:

$40$
