Answer-
The measurement of angle A' will be 130° .
Solution-
Transformations like - rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.
It doesn't matter the order or how much degree of rotation has taken place, the final image will be congruent to the original image.
So, even after the rotation of 90° clockwise around the origin, the measurement of angle A will be 130° and so do all the rest of the angles.
