Answer:
x = 144°
Step-by-step explanation:
In the figure given , two regular polygons are given to us. Since the polygon has five sides , it is a regular Pentagon. We know that each angle of a regular Pentagon is 108° .
So , here as per figure two regular Pentagons are attached base to base . Now , we know that,
- Measure of complete angle is 360° .
- Measure of regular polygon's angle is 108°.
According to Question ,
⇒ 108° + 108° + x = 360°
⇒ 216° + x = 360°
⇒ x = 360° - 216°
⇒ x = 144°
<h3>
<u>Hence</u><u> </u><u>the</u><u> value</u><u> of</u><u> x</u><u> is</u><u> </u><u>1</u><u>4</u><u>4</u><u>°</u><u> </u></h3>
In order to determine the cost of each pencil we have to divide the total cost for the package of pencils by the number of pencils contained
For the 4 pencils box:
Cost per pencil = Total cost/number of pencils
Cost per pencil = 6/4 = 1.5
Similarly, for the 5 pencils package:
Cost per pencil = 7/5 = 1.4
As you can see, the $7 package is better to buy, because each pencil costs $1.4, then, option A is the correct answer
