Answer:
8.5= w -12 (add 12 to both sides)
20.5= w
Step-by-step explanation:
The length of BC = 72
Solution:
Given ΔABC and ΔDEF are similar triangles.
ΔABC
ΔDEF
AB = 54, BC = n, EF = 12, DE = 9
Similar triangle theorem:
If two triangles are similar then the corresponding sides are proportional to each other.

Substitute the given values, we get

Do cross multiplication.

Divide both sides of the equation by 9.



⇒ BC = 72
Option B is the correct answer.
The length of BC = 72.
(4,-2)(5,0)
slope(m) = (0 - (-2) / (5 - 4) = 2/1 = 2
there is going to be 2 possible answers...
y - y1 = m(x - x1)
now we sub
using points (4,-2)..... y -(-2) = 2(x - 4) =
y + 2 = 2(x - 4) <==
using points (5,0)....y - 0 = 2(x - 5) <==
Answer:
It would be about 1/4
