The measure of an angle is 43.5 degrees . What is the complementary angle?

A complimentary angle has to add up two angles to equal 90 degrees.

We have one angle which is 43.5 degrees, so all we have to do is subtract 43.5 degrees from 90 degrees to find the missing angle.

90 degrees minus 43.5 degrees is 46.5 degrees.

That means the missing angle is 46.5 degrees.

The measures of the angles don't change when you translate a figure, because the entire figure is moving as a whole. Imagine having a paper parallelogram, moving it around and flipping it over. Not even dilations would change these angles (for reasons that can be pretty easily visualed but not really proven until geometry)

$m\angle A'=125\°$
