Answer:
n = 13
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
Set (n - 2)180 equal to 1980 and solve for n.
(n - 2)180 = 1980
Divide both sides by 180.
n - 2 = 11
Add 2 to both sides.
n = 13
B. 4 cm, 10 cm, and 15 cm
According to two sides, 4, and 10 cm, the third side has to be between
10-4 and 10+4
6<side length<14
However, the side length is 15 cm, greater than 14 cm, so it is not a triangle.
Hope this helps :)
