## Edge Length of Pentagon given Height using Central Angle Solution

STEP 0: Pre-Calculation Summary
Formula Used
Edge Length of Pentagon = (2*Height of Pentagon*sin(pi/5))/(1+cos(pi/5))
le = (2*h*sin(pi/5))/(1+cos(pi/5))
This formula uses 1 Constants, 2 Functions, 2 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Functions Used
sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
Variables Used
Edge Length of Pentagon - (Measured in Meter) - The Edge Length of Pentagon is the length of one of the five sides of the Pentagon.
Height of Pentagon - (Measured in Meter) - Height of Pentagon is the distance between one side of Pentagon and its opposite vertex.
STEP 1: Convert Input(s) to Base Unit
Height of Pentagon: 15 Meter --> 15 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
le = (2*h*sin(pi/5))/(1+cos(pi/5)) --> (2*15*sin(pi/5))/(1+cos(pi/5))
Evaluating ... ...
le = 9.74759088698719
STEP 3: Convert Result to Output's Unit
9.74759088698719 Meter --> No Conversion Required
9.74759088698719 9.747591 Meter <-- Edge Length of Pentagon

## What is Pentagon?

A Pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting. A simple pentagon (5-gon) must have five straight sides that meet to create five vertices but do not intersect with each other. A self-intersecting regular pentagon is called a pentagram.
