∆ABC rotates around point D to create ∆A′B′C′.

Answer:
The coordinates of A' are (4,1). Therefore the coordinates of A'' are (11,2).
Step-by-step explanation:
From the figure it is clear that the coordinates of triangle ABC are A(4,9), B(4,6) and C(2,6).
The ∆ABC rotates around point D to create ∆A′B′C′. The vertices of image are B'(4,4) and C'(6,4).
From the figure it is clear that ∆ABC rotates 180° around point D to create ∆A′B′C′.
The coordinates of A' are
The coordinates of A' are (4,1).
If ∆A′B′C′ rotates 90° counterclockwise around point E(7, 5) to form triangle ∆A″B″C″, then
The coordinates of A'' are
Therefore the coordinates of A'' are (11,2).
