pi = 180 degrees
pi / 2 = 90 degrees
2 pi = 360 degrees
so pi / 5 = 180 / 5 = 36
36 x 4 = 144 degrees
a 144 degree angle is obtuse

When given a circumference how do you find the area?
A = C^2/(4 pi) The area of the circle is... The circumference squared... divided by 4... divided by pi If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference! C = (A*(4 pi))^(1/2)
How do you find the angle of a circle divided into 8 equal parts?
There are 2pi in a circle. If we divide a circle into 8 equal parts, then each part will be pi/4, [(2pi)/8].
How was it determined that the tangent of pi divided by 4 is 1?
As tan(x)=sin(x)/cos(x) and sin(pi/4) = cos(pi/4) (= sqrt(2)/2) then tan(pi/4) = 1
