A pentagon is a closed 5 sided polygon.
A regular polygon has all sides equal as well as all angles equal.
°The formula to find the sum of all angles of a polygon is = (n-2) ×180
So for a pentagon, n= 5
So the sum of all the angles must be (5-2)× 180= 3 × 180 = 540.
Now as it is a pentagon, it shall have 5 vertices.
So there are 5 angles in a pentagon and all must be equal.
Hence each interior angle must be 540/5 = 108
So for a regular polygon with 5 sides must have each interior angle = 108
In order to get your answer, take the number of text messages you send each day (12) and subtract it from the number you and your sister send (26). When you get the answer from subtracting both of these numbers, take the answer from your subtraction and add it to the number of text messages that you send a day (12).

Answer:
mean is 16
Step-by-step explanation:
Answer:
Part a)
Part b)
Step-by-step explanation:
Let
x ----> the number of miles driven
y ----> the total cost
we know that
<em>First Plan</em>
----> equation A
<em>Second Plan</em>
----> equation B
Part a) For what amount of driving do the two plans cost the same?
Equate equation A and equation B and solve for x
Part b) What is the cost when the two plans cost the same?
For x=350 miles
substitute in equation A or equation B (the cost will be the same)
