Given information
A pyramid with height 
and base an equilateral triangle with side 
Step-by-step explanation
Step 1.
Pyramid's lateral sides are nothing but equilateral triangle with each angle having measure 
.
.
Which gives us, 
.
.Here, it is also given that each side's measure is .
.So, 
Now 
is the perpendicular from 
which bisects base side 
.
is the perpendicular from which bisects base side .So, 
.
.Now, we will use a Trigonometric identity of sides of an triangle.
This is height of the triangle.
