Chord Length of Fourstar Solution

STEP 0: Pre-Calculation Summary
Formula Used
Chord Length of Fourstar = sqrt(2*Edge Length of Fourstar^2*(1-cos(Outer Angle of Fourstar)))
lc = sqrt(2*le^2*(1-cos(Outer)))
This formula uses 2 Functions, 3 Variables
Functions Used
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Chord Length of Fourstar - (Measured in Meter) - The Chord Length of Fourstar is the distance between any two adjacent spike tips of the Fourstar from one tip to other tip.
Edge Length of Fourstar - (Measured in Meter) - The Edge Length of Fourstar is the length of any edge of the Fourstar shape from one end to other end.
Outer Angle of Fourstar - (Measured in Radian) - The Outer Angle of Fourstar is the angle between adjacent isosceles triangle or the triangular spikes that attached to the square of the Fourstar.
STEP 1: Convert Input(s) to Base Unit
Edge Length of Fourstar: 5 Meter --> 5 Meter No Conversion Required
Outer Angle of Fourstar: 165 Degree --> 2.8797932657901 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
lc = sqrt(2*le^2*(1-cos(∠Outer))) --> sqrt(2*5^2*(1-cos(2.8797932657901)))
Evaluating ... ...
lc = 9.91444861373775
STEP 3: Convert Result to Output's Unit
9.91444861373775 Meter --> No Conversion Required
FINAL ANSWER
9.91444861373775 9.914449 Meter <-- Chord Length of Fourstar
(Calculation completed in 00.004 seconds)
