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

STEP 0: Pre-Calculation Summary
Formula Used
diagonal_across_5_sides = (Diagonal across four sides/(sqrt(5+2*sqrt(5))))*(1+sqrt(5))
d5 = (d4/(sqrt(5+2*sqrt(5))))*(1+sqrt(5))
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Diagonal across four sides - Diagonal across four sides is a straight line joining two opposite sides which is across four sides of the given polygon. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Diagonal across four sides: 9 Meter --> 9 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d5 = (d4/(sqrt(5+2*sqrt(5))))*(1+sqrt(5)) --> (9/(sqrt(5+2*sqrt(5))))*(1+sqrt(5))
Evaluating ... ...
d5 = 9.4631600181444
STEP 3: Convert Result to Output's Unit
9.4631600181444 Meter --> No Conversion Required
9.4631600181444 Meter <-- Diagonal across five 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.
