Answer:

BC=9 miles

Explanation:

ABC~EDC

12/8=x/6

6(12)=8x

72=8x

x=9

Answer:

BC = 9 miles

Explanation:

Here, we are given ΔABC ∼ ΔEDC, which means both triangles are similar and they tend to have the same dimensions and properties.

To find the length of BC, we are given the proportion:


(12)/(8) = (x)/(6)

Where x represents the length BC.

Solving further, let's cross multiply


12 * 6 = 8x


72 = 8x

Solving for x, we have:


8x = 72

Lets divide both sides by 8


(8x)/(8) = (72)/(8)


x = 9

Therefore the distance BC is 9 miles
