Question

given ( m parallel n ), find the value of ( x ) and ( y ).
answer attempt 3 out of 4
( x=quad y= )

Explanation:

Step1: Use the property of alternate interior angles

Since \(m\parallel n\), the angle \(x\) and the \(39^{\circ}\) angle are alternate interior angles. So \(x = 39\).

Step2: Use the property of linear - pair angles

The angle \(y\) and the \(39^{\circ}\) angle form a linear - pair. So \(y+39 = 180\), then \(y=180 - 39\).

$$y = 141$$

Answer:

\(x = 39\), \(y = 141\)
