The best answer is C : The sum of the measures of two angles os 180 degrees .
Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon

Here n is the number of sides of polygon
In the given polygon
n = 7
So,

Hence,
The sum of interior angles of given polygon is 900°
Answer:
Step-by-step explanation:
A truck drove 229.77 miles on 11.1 gallons of gas.
<u>Find the mileage per gallon:</u>
<u>Find the distance can be driven on full tank:</u>
- 20.7 * 16.8 = 347.76 miles
Find the change
the change is 63-21=42
42 degrees in 12 hours
we want to find xdegrees/1hour
42/12=3.5 degrees per hour
