Need help with number 13

blsea [12.9K]

Answer:

x = 19

Step-by-step explanation:

the question tells you that the angle CBD is 90°.

so, that means that angle DBE and angle CBE add up to 90.

using this, you can make the following equation:

2x - 1 + 5x - 42 = 90

2x + 5x + -43 = 90

7x - 43 = 90

add 43 to both sides

7x = 90 + 43

7x = 133

x = 133/7

x = 19

Volume

CaHeK987 [17]

Answer:

3.75 feet.

Step-by-step explanation:

Given:

The volume of a right octagonal prism is 30 cubic feet.

The area of the octagonal base is 8 square feet.

Question asked:

What is the height of the prism ?

Solution:

As we know:

 $Volume\ of \ octagonal-prism=base\ area\times height$

$30=8\times height\\ \\ By\ dividing\ both\ sides \ by\ 8\\ \\ \frac{30}{8} =\frac{8}{8} \times height\\ \\ 3.75=height$

Therefore, height of the prism is 3.75 feet.
