5. Find the value of x that makes BC || DE.

s344n2d4d5 [400]

Answer:

x = -7

Step-by-step explanation:

To find the value of x, you need to set up a proportion:

$\frac{x-2}{15}$ = $\frac{x-1}{18}$

Then cross multiply:

15x - 15 = 18x + 36

Then subtract 15x from both sides:

-15 = 3x + 36

Subtract 36 from both sides:

-51 = 3x

Finally, divide both sides by 3:

x = -7

1. The diameter of one side of a 10-foot log is approximately 13 inches. The diameter of the other side of the log is approximat

LuckyWell [14K]

To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³
