The measure of angle XYZ in the parallelogram is: 71°.
<h3>What are the Opposite Angles of a Parallelogram?</h3>
In a parallelogram, the angles that are opposite each other are congruent.
Find m∠XWZ using the triangle sum theorem:
m∠XWZ = 180 - m∠WXZ - m∠WZX
m∠XWZ = 180 - 81 - 28
m∠XWZ = 71°
m∠XWZ = m∠XYZ [opposite angles are congruent]
m∠XYZ = 71°

The common difference is essentially what u need to add to one number in the sequence to get the next
So previous number + common difference = next number after that
The common difference would be -8
There would be 5 buses and 9 extra seats because 5 x 52 is 260 and you need 251 and there would be 9 extra seats
you cannot get that answer.... when you divide. Put the number into a fraction first so, it makes it easier to see what you are doing. So,

.Now simplify the cross off the zero from the top and the bottom to get

. So,

will give you 0.83333333333...3.
