How many sides does a polygon have if the sum of its angle measures is 2700 degrees and how do you find this?
The number of angles equal the number of sides
The number of angles calculate: (n-2)x180°
(n-2)x180°=2700° |divide both sides by 180°
n-2=15 |add 2 to both siedes
n=13
Answer: 13 sides.
\(the\ sum\ of\ angle\ measures\ is\ 2700^0\\\\(n-2)\cdot180^0=2700^0\ -the\ number\ of\ the\ sides\ of\ the\ polygon\\\ -2= \frac{2700}{180} \ \ \ \Rightarrow\ \ \ n-2=15\ \ \ \Rightarrow\ \ \ n=17\\\\Ans.\ 17\ sides\ of\ the\ polygon.\)
