Question

given ( mparallel n ), find the value of x.

Explanation:

Step1: Use the property of adjacent angles

When two angles are adjacent and form a linear pair, their sum is \( 180^{\circ} \).
So, \( x + 76=180 \)

Step2: Solve for \( x \)

Subtract \( 76 \) from both sides of the equation:
\( x=180 - 76 \)
\( x = 104 \)

Answer:

\( x = 104 \)
