WXYZ is a parallelogram. Find the measure of angle Z

Delvig [45]

Given:

The figure of a parallelogram.

To find:

The measure of angle Z.

Solution:

We know that, the consecutive interior angles of a parallelogram are supplementary angles, it means there sum is 180 degrees.

In the given figure angle W and angle Z are supplementary angle. So,

$m\angle W+m\angle Z=180^\circ$

$(18b-11)^\circ+(9b+2)^\circ=180^\circ$

$(27b-9)^\circ=180^\circ$

$(27b-9)=180$

Adding 9 on both sides, we get

$27b=180+9$

$27b=189$

$b=\dfrac{189}{27}$

$b=7$

Now,

$m\angle Z=(9b+2)^\circ$

$m\angle Z=(9(7)+2)^\circ$

$m\angle Z=(63+2)^\circ$

$m\angle Z=65^\circ$

Therefore, the correct option is C.

Max delivers 8520 pieces of mail in one year. If you delivered the same number of pieces of mail each month about how many piece

valentinak56 [21]

So first we want to know how much mail he delivered in one month
8520/12 = 710 mails per month
there are 12 months, so we divide by 12 to find for one month
The answer we divide by two to find for 2 months.
710 times 2 = 1420 mails per 2 months.
