@Jdoe0001 already gave you a hint in the comment section, and that's a real giveaway, but I'll expand on the hint.
Complimentary angles add up to 90°, and A and B are complimentary, then A+B = 90°. A proof.
Substitute. 42° + B = 90°.
B = 90° - 42°
B = 48°
Hope this helps!

A two-dimensional figure is a flat figure that is described by its length of sides only. It can be obtained from a three dimensional solid when sliced or truncated.
Truncation is the process of cutting a solid with respect to a given plain. Therefore, when a three dimensional solid is truncated, the face forms a two dimensional figure. An example is when a cube is truncated horizontally, a square can be obtained at the surface.
