Given
and 
Required
The relationship between them and
From the question, we understand that and are supplementary
Supplementary angles add up to 180.
So, the relationship between and is:
The height of the triangular base of the pyramid is calculated through the equation,
h = (cos x)(18 in)
where h is height and x is half of the angle of the triangle. Since the triangle is equilateral, the value of x is 30°. Substituting,
h = (cos 30°)(18 in)
h = 15.59 in
Thus, the height of the base is approximately 15.59 inches.
