Answer:
see below
Explanation:
Pre-image: A(3, 8), B(3, 3), C(7, 3)
Reflection in the x-axis changes the y-coordinate sign:
A'(3, -8), B'(3, -3), C'(7, -3)
Reflection in the y-axis changes the x-coordinate sign:
A''(-3, -8), B''(-3, -3), C''(-7, -3)

Comment
We have assumed that the first image is reflected again to get the second image. If the second image is supposed to be a reflection of the pre-image, then only the sign of x will change from the pre-image coordinates.
There are no "rotated" images; only reflected ones. (Though, after the second reflection, the image could be considered to be a 180° rotation of the pre-image.)
