We know that
<span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles
</span>therefore
[the area of <span>a regular nonagon]=9*[area of isosceles triangle]
</span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm²
so
[the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²
the answer is
1390.5 cm²
Answer:
22
Step-by-step explanation:
Working backwards
1+1 then x2 is 4
4+1 then x2 is 10
10+1 then x2 is 22
Find the slope of A. The slope of a line parallel to A would have the same slope of A. Remember, slope=rise over run.
