The sum of the interior angles of a polygon with N sides is (N-2) x 180 degrees.
For a 30-gon, the sum of interior angles is (28) x (180) = <u>5,040 degrees</u>.
It makes no difference whether or not the polygon is convex at every vertex.
Answer:
volume of hexagonal prism = area of base * perpendicular height
Step-by-step explanation:
The system of inequalities is x+y≥250 and 3x+2y≤800.
Step-by-step explanation:
Given,
People to invite = at least 250
At least 250 means that the number can increase from 250.
Cups to be provided = only 800
It means the number cannot exceed 800.
Number of adults = A
Number of children = C
According to given statement;
x+y≥250
3x+2y≤800
The system of inequalities is x+y≥250 and 3x+2y≤800.
