So it's easier to calculate if you figure out how much time it took her to finish 25% of the wall. Since it took her 45 minutes to do 75%, it took her 15 minutes to do 25%. Then you just multiply.
Therefore, it takes her 60 minutes to finish building her wall.
The angles m∠x = m∠y because alternate interior angles are equal.
<h3>What is a
parallelogram?</h3>
A parallelogramis a quadrilateral in which opposite sides are equal and parallel to each other.
The opposite angles are also congruent, whereas consecutive interior angles are supplementary.
In the quadrilateral ABCD:
m∠x = m∠y (alternate interior angles are equal)
The angles m∠x = m∠y because alternate interior angles are equal.

I believe its 1.8
hope this helps :)
