Answer:
162°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 20, thus
sum = 180° × 18 = 3240°, thus
1 interior angle = [tex]\frac{3240}{20}[/tex] = 162°
Answer: [tex]3240^{0}[/tex]
Step-by-step explanation:
The formula for finding the interior angle of a polygon is given as :
[tex](n-2)180[/tex]
where n is the number of sides
substituting the value of n , we have
[tex](20-2)180[/tex]
which will be 18 x 180
therefore, the interior angle of a 20-sided polygon is [tex]3240^{0}[/tex]
