Question

a) How many diagonals doesa regular hexagon?

b) Find the angle sum of a convex polygon with number of side is 10​

Answer 1

Answer:

a) 2

b) Answer: The sum of angles in a convex 10-sided polygon is equal to 1440°. We will use the shape of the decagon to find the sum of angles.

Step-by-step explanation:

Answer 2

Answer:

MARK ME AS BRAINLIEST

a)The number of diagonals of an n sided polygon is given by Dn=2n(n−3)

A convex regular hexagon has 6 sides. 

So, n=6 

∴D6=26(6−3)=9

b)angle=1440°
