The sum of the interior angles of a polygon is.
Sum = 180(n-2) where n is the number of sides
Thus 180(n-2) = 3780
n-2=3780/180 =21
⇒ n = 21+2 = 23
number of sides is 23
Answer:
A =80.5 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
The base is 14 ft and the height is 11.5 ft
A = 1/2 * 14 * 11.5
A =80.5 ft^2
Answer:
