A restaurant owner is trying to decide whether to stay open at lunchtime. She has far fewer customers at lunch than at dinner and the revenue she brings in from lunch covers her expenses to buy food and pay the staff, but not much more.
What should the restaurant owner do?

Explanation:

A restaurant owner should not close the restaurant over the lunchtime. He should only do that if he is sure that he won't have any customer over lunchtime but since he has fewer of them, she should open it.

Also, it is giving him the ability to pay for some of the expenses which is also good for the restaurant.

answer with step-by-step explanation:

a. wx is perpendicular to xy - true:

(since x is adjacent to x and y and all angles are 90 degrees in a square, therefore wx is perpendicular to xy)

b. ∠w is congruent to ∠x - true:

(all angles in a square are equal to each other)

c. ∠w is supplementary to ∠x - true:

(∠w and ∠x both are right angles which add up to 180 degrees so they are supplementary angles)

d. wxyz is a rhombus - true:

(a rhombus has all sides equal in length and so has a square so it is a rhombus)

e. wxyz is a trapezoid - false:

(a trapezoid has only one pair of parallel sides while a square has two pairs of parallel sides)

f. wx is parallel to yz - true:

(wx and yz are parallel to each other)
