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.

X+5.75
X is the child's ticket and it is 5.75 less than the adults, turn it into an equation by flipping it
To do this you would first calculate the 4% commission:
0.04 *8000 = 320.
And then the 8% commission:
0.08 * (9000 - 8000) = 80.
Now you add the two values together to get the answer, 320 + 80 = 400.
Your commission would be $400.
Hope this helps.
Answer: Yes
Step-by-step explanation:
Each value of y maps onto one value of x.
