Question

given ( mparallel n ), find the value of ( x ).
answer attempt 1 out of 2
( x=)

Explanation:

Step1: Use the property of alternate interior angles

Since \(m\parallel n\), the angles \((8x - 4)^{\circ}\) and \((9x - 7)^{\circ}\) are equal. So, \(8x-4=9x - 7\).

Step2: Solve the equation for \(x\)

Subtract \(8x\) from both sides: \(-4=x - 7\).
Add \(7\) to both sides: \(x=3\).

Answer:

\(3\)
