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-

The height of the triangular base of the pyramid is in

Solution-

The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 18 inches.

i.e the side length of an equilateral triangle is 18 inches.

from properties of equilateral triangle we know that,

Putting the values,

Therefore, the height of the triangular base of the pyramid is in

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
