Answer:

x=5

Step-by-step explanation:

We can use ratios to solve

CB        CD

------ = -----------

CA          CE

5x       20

----  = --------

45       36

Using cross products

5x * 36 = 45* 20

180x = 900

Divide by 180

x = 900/180

x =5

Cross multiply the 5x and 36 as well as the 45 and 20

180x=900

Then, divide the 900 by 180

Find the vol of this prism
polet [3.4K]

Answer:

V = 396 cm³

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h the height of prism )

A = \frac{1}{2} bh ( b is base and h perpendicular height )

here b = 9, h = 8 , then

A = \frac{1}{2} × 9 × 8 = 4.5 × 8 = 36 cm² , so

V = 36 × 11 = 396 cm³
