The correct answer is A. 124°
Further explanation:
First of all we will have to define alternate interior angles.
"When two parallel lines are intersected by a traversal, the angles which are formed inside the parallel lines are called alternate interior angles"
In the given figure,
The alternate angles are:
m∠O and m∠X
m∠W and m∠P
We are given that m∠W is 124°.
The alternate angles' theorem states that the alternate angles are equal.
So through the theorem,
m∠W = m∠P = 124°
The correct answer is A. 124°
