Answer:

Q1

Sum of interior angles on n-sides polygon is:

• S = (n - 2)*180°

Sum of interior angles of a hexagon (6-sided polygon):

• S = (6 - 2)*180° = 4*180° = 720°

Q9

Sum of exterior angles of any polygon is 360°

Each exterior angle of a pentagon is:

• 360°/5 = 72°

Answer 2

Answer:

In a n -sided polygon, sum of its interior angles is (n−2)×180∘ , hence sum of the interior angles in a convex hexagon is (6−2)×180∘=720∘ .
