Answer:
(a) 8√3
Step-by-step explanation:
All of the triangles are similar, so the ratio of hypotenuse to long side is the same for all. Comparing the middle-size triangle to the largest, we have ...
... x/12 = 16/x
... x² = 192 . . . . . . . . . . . . . multiply by 12x; next take the square root
... x = √192 = 8√3 . . . . . . seems to match answer choice (a)
The answer is that if polygon ABCD rotates 90 counterclockwise
to create a'b'c'd', then the coordinates of d will be at the location (-2, 2)
and if the polygon ABCD rotates 180 clockwise to create a'b'c'd'
the coordinate of A will become (3,-1).
