Question

sum of all interior angles of a regular polygon is 18 right angles. Then find
the number of sided of the polygon​

Answer 1

the answer is 9.

since there are 18 right angles, the sum of all angles is 1620 degrees

(x-2)180=1620

(x-2)=1620÷180

(x-2)=9

x=9+2

x=11

Answer 2

Answer:

Step-by-step explanation:

Sum of all interior angle's of a polygon = (n-2)180⁰

Now,

(n-2)180 = 18×90⁰(18 right angle's)

=(n-2). = 1620⁰÷180

=n. = 9+2

=n. = 11 side's

11 Sided Polygon.
