Answer:

$BC=24\ units$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

Triangle ABC is an isosceles triangle

because

m∠B=m∠C

therefore

AC=AB

substitute the given values

$x+8=2x-1$

solve for x

$2x-x=8+1\\x=9$

Find the length of side BC

$BC=3x-3$

substitute the value of x

$BC=3(9)-3=24\ units$

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

the answer is

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