The area of the regular nonagon is 270 sq cm.
Step-by-step explanation:
Given,
Each side of a regular nonagon (b) = 10 cm
The length of apothem (h) = 6 cm.
To find the area of the nonagon.
Formula
The area of a nonagon with b as each side and h as apothem is = 9(
bh)
Now,
Putting the value of h and b we get,
Area = 9(
×10×6) sq cm = 270 sq cm
Hence, the area is 270 sq cm.
By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
The answer would 2, since you cannot divide anything by 0 as it would be undefined. 2 is the only number that gives you this option
