Answer:
AC = 14.0
Step-by-step explanation:
We know that this is a non-right triangle, so we must use either the law of sines or law of cosines to find AC.
We can find the measure of <C using 180 - (118 + 22) = 40
Since we only know one side and all the angles, we can use the law of sines:
Solving for AC gives us AC = 13.986826, which we can round to 14.0
The area of a regular octagon is:
A = a * P / 2, where a is an apothem and P is a perimeter.
P = 8 * 8 m = 64 m
A = 9.7 m * 64 m / 2
A = 620.8 / 2 m²
A = 310.4 m²
Answer:
The area of a regular octagon is 310.4 m².
Hope this helps!
