## Outer angle of Fourstar Solution

STEP 0: Pre-Calculation Summary
Formula Used
Outer Angle of Polygram (in Degrees) = Inner Angle of Polygram (in Degrees)+(pi/2)
β = α+(pi/2)
This formula uses 1 Constants, 1 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Inner Angle of Polygram (in Degrees) - Inner Angle of Polygram (in Degrees) is the angle of the isosceles triangle attached to sides of the n-sided polygon. (Measured in Degree)
STEP 1: Convert Input(s) to Base Unit
Inner Angle of Polygram (in Degrees): 30 Degree --> 0.5235987755982 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
β = α+(pi/2) --> 0.5235987755982+(pi/2)
