For this you need to use the reverse cosine function
Cos^-1 (.25)
75.6
I’m pretty sure the angle in 53 degrees
Answer:

Step-by-step explanation:
The equation to find the area of a semi circle is (Area= Pi * Radius^2 / 2)
The equation I created was 3.14*6^2/2 and after calculating is how I came up with the answer.
Hey! the answer would be A regular 40-sided polygon has an interior angle equal to:
(40 - 2) (180) /40 = 171 degrees
The interior angle is also the smallest angle that is needed to rotate the polygon and map it unto itself. So, the smallest degree of rotation needed to map the polygon back to itself is 171 degrees.
