The count of the equilateral triangle is an illustration of areas
There are 150 small equilateral triangles in the regular hexagon
<h3>How to determine the number of
equilateral triangle </h3>
The side length of the hexagon is given as:
L = 5
The area of the hexagon is calculated as:
This gives
The side length of the equilateral triangle is
l = 1
The area of the triangle is calculated as:
So, we have:
The number of equilateral triangles in the regular hexagon is then calculated as:
This gives
So, we have:
Rewrite as:
Hence, there are 150 small equilateral triangles in the regular hexagon

I will help up you using these statements which I took for the same problem:
a) at the lowest position of the bob, the KE is equal to zero.
FALSE BECAUSE AT THE LOWEST POSITION THE PE IS THE LOWEST AND THE KE IS THE HIGHEST.
b) at the highest position of the bob, the PE is equal to zero.
FALSE BECAUSE AT THE HIGHEST POSITION THE PE IS THE HIGHEST
c) at the highest position of the bob, the KE is equal to zero.
TRUE: AT THE HIGHEST POSITION THE PENDULUM COMES TO ZERO SPEED AND SO THE KE IS ZERO.
d) at all the positions except the highest positions the PE is zero.
FALSE: THE PE ENERGY CHANGES WITH THE ALTITUDE AND IS ZERO ONLY AT THE BASE LEVEL.
