Answer:
<em>Perimeter of ΔMNK is </em><em>6 in.</em>
Step-by-step explanation:
<u>Midpoint Theorem-</u>
It states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
M, N and K are the midpoints of the sides.
So,
Perimeter of a ΔABC is 12 in, i.e in
Perimeter of ΔMNK is,
in
step 1. what is the question? solve for k? okay.
step 2. 4(k - 6) = 6(-4 - 5k)
step 3. 4k - 24 = -24 - 30k
step 4. 34k = 0
step 5. k = 0.
The slope is 0, then the line is horizontal.
y = 6
