Sum of interior and exterior angle is 180 so
Interior angle =180−72=108
Now we need to find the no of sides of the polygon= n We know that interior angle of n-sides is given by
(n−2)×180n
We have
(n−2)×180=108n
or
180n−360=108n
or
72n=360
n=5 sides so there are 5 angles each of 108 degrees Sum of the interior angles=108+108+108+108+108=540.....
<span>To find the measure of each exterior angle of a regular polygon, you just divide 360 degrees by the number of sides.

Hello!

❖ The area is 169 square cm.
Find the value of each side (a square has 4 sides so divide by 4 ):
52/4 = 13
To find the area of a square, you only need 2 sides so multiply 2 sides:
13 x 13 = 139
Area = 139 square cm

Y=-3x+5 because the line crosses the y-axis at (0,5) and the slope is -3 because the rise/run saying it goes down 3 and over 1 which can be simplified to -3.
Answer:
Pauli's pizzeria make more money per pizza
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find out the slope of the graph of Leo's pizzeria
looking at the graph take the point (2,24)
The graph show a proportional relationship (the line passes through the origin)
The slope is m=y/x
we have
For x=2, y=24
substitute
m=24/2=$12 per pizza sold
The linear equation is
y=12x
step 2
Compare the slopes
<em>Pauli's pizzeria</em>
we have
y=15x -----> slope m=$15 per pizza sold
<em>Leo's pizzeria</em>
we have
y=12x -----> slope m=$12 per pizza sold
$15 per pizza sold > $12 per pizza sold
therefore
Pauli's pizzeria make more money per pizza
