a right pyramid with a square base has a base edge length of 24 feet and slant height of 20 feet what is the height of the pyram

Sphinxa [80]

Let

l-------> the slant height of the right pyramid

b------> the length side of the square base of the right pyramid

h------> the height of the right pyramid

we know that

Applying the Pythagorean Theorem

$l^{2} =h^{2}+(\frac{b}{2})^{2}$

Solve for h

$h^{2}=l^{2}-(\frac{b}{2})^{2}$

in this problem we have

$l=20\ ft\\\frac{b}{2} =\frac{24}{2} =12\ ft$

Substitute in the formula

$h^{2}=20^{2}-12^{2}$

$h^{2}=256$

$h=16\ ft$

therefore

<u>the answer is</u>

The height of the right pyramid is $16\ ft$

Anyone know the answer? Also could you put down what equation I’m supposed to use?

goldenfox [79]

Answer:

The bottom two are your answers.

Step-by-step explanation:

What you do is use the slope formula which is y_2-y_1/x_2-x_1.

So for PQ it will be 12(which is y_2)-6(which is y_1)/4(which is x_2)-5(which is x_1) which equals -6.

12-6/4-5=-6.
