the base of a solid oblique pyramid is an equilateral triangle with a base edge length of 18 inches. what is the height of the triangular base of the pyramid? 9√2 in. 9√3 in. 18√2 in. 18√3 in.

Answer

Explanation:

Step1: Recall height - formula for equilateral triangle

For an equilateral triangle with side length (a), the height (h) is given by (h = \frac{\sqrt{3}}{2}a).

Step2: Substitute (a = 18) into the formula

We have (h=\frac{\sqrt{3}}{2}\times18 = 9\sqrt{3}) inches.

Answer:

B. (9\sqrt{3}) in.
