AB = 18 BC=8 CD=5

Let's call E that point at the other end of x, so x=DE.

Secant Secant theorem says

CE × CD = AC × BC

and since CE = CD + DE, AC = AB + BC

(CD + DE) CD = (AB + BC) BC

Substituting,

(5 + x)(5) = (18 + 8) (8)

5 + x = (26)(8)/5

x = -5 + (26)(8)/5 = 183/5 = 36.6

Answer: 36.6, last choice

Step-by-step explanation:

<u>Volume Of A Pyramid </u>

The volume of a pyramid is computed as one third of the product of the area of the base (B) by the height (H):

$\displaystyle V=\frac{1}{3}BH$

<em>The question doesn't ask for anything in particular, so I'm computing the volume of the solid shown in the image </em>

We have a rectangular base of dimensions 15m x 60 m. The area of the base is

$B=(15m)(60m)=900m^2$

We now calculate the volume, knowing the height is 55 m

$\displaystyle V=\frac{1}{3}(900\ m^2)(55\ m)$

$\boxed{\displaystyle V=16500\ m^3}$
