## Diagonal of Decagon across three sides given diagonal across five sides Solution

STEP 0: Pre-Calculation Summary
Formula Used
diagonal_across_3_sides = ((Diagonal across five sides/((1+sqrt(5))))/2)*sqrt(14+6*sqrt(5))
d3 = ((d5/((1+sqrt(5))))/2)*sqrt(14+6*sqrt(5))
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Diagonal across five sides - Diagonal across five sides is a straight line joining two opposite sides which is across five sides of the given polygon. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Diagonal across five sides: 11 Meter --> 11 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d3 = ((d5/((1+sqrt(5))))/2)*sqrt(14+6*sqrt(5)) --> ((11/((1+sqrt(5))))/2)*sqrt(14+6*sqrt(5))
Evaluating ... ...
d3 = 8.89918693812442
STEP 3: Convert Result to Output's Unit
8.89918693812442 Meter --> No Conversion Required
8.89918693812442 Meter <-- Diagonal across three sides

## What is a decagon?

Decagon is a polygon with ten sides and ten vertices. A decagon, like any other polygon, can be either convex or concave, as illustrated in the next figure. A convex decagon has none of its interior angles greater than 180°. To the contrary, a concave decagon (or polygon) has one or more of its interior angles greater than 180°. A decagon is called regular when its sides are equal and also its interior angles are equal.
