Question

The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 14 units

Answer 1

Answer:

A solid right pyramid has a square base. The base edge length is 2 cm longer than the height of the pyramid.

If the height is 6 cm, the volume of the pyramid is

128

Answer 2

given : The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 14 units.

What is BC, the height of the pyramid?

solution:

using the trigonometry ratios

. We see that a right triangle is being formed where the height is involved. therefore ,

$\tan 45 = \frac{opposite side}{adjacent side} \\\\\tan 45 = \frac{height }{14} \\\\\tan 45^\circ = 1\\\\1 = \frac{height }{14}\\\\height = 14 units$

hence , The height of the pyramid is 14 units
