Question

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

Explanation:

Step1: Use the property of alternate interior angles

When two parallel lines \(m\parallel n\) are cut by a transversal \(t\), alternate interior angles are equal.
The angle of \(45^{\circ}\) and \(x\) are alternate interior angles.

Answer:

\(x = 45\)
