Answer:
D. reflection across a vertical line
Step-by-step explanation:
Reflection is basically a mirror image. Since you can see that the first triangle is flipped over to get the second one, this is a reflection.
It is not a vertical translation; this means that the triangle shifted up or down.
It is not a horizontal translation, this means that the triangle shifted left or right.
It is not a rotation about point A either, this would have meant that the triangle spun around.
If you round up the 27.64 to 28 and then multiply it bye 3 it eaquals 84
Isolate the variable by dividing each side by factors that don't contain the variable.
l = v/wh
w
h
