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

STEP 0: Pre-Calculation Summary
Formula Used
diagonal_across_2_sides = (((2*Diagonal across three sides)/(sqrt(14+6*sqrt(5))))/2)*sqrt(10+2*sqrt(5))
d2 = (((2*d3)/(sqrt(14+6*sqrt(5))))/2)*sqrt(10+2*sqrt(5))
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Diagonal across three sides - Diagonal across three sides is a straight line joining two opposite sides which is across three sides of the given polygon. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Diagonal across three sides: 7 Meter --> 7 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d2 = (((2*d3)/(sqrt(14+6*sqrt(5))))/2)*sqrt(10+2*sqrt(5)) --> (((2*7)/(sqrt(14+6*sqrt(5))))/2)*sqrt(10+2*sqrt(5))
Evaluating ... ...
d2 = 5.08579769603753
STEP 3: Convert Result to Output's Unit
5.08579769603753 Meter --> No Conversion Required
5.08579769603753 Meter <-- Diagonal across two 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.
