an acute angle
If they are the angles of a triangle then the missing angle is 116 degrees
The supplementary angle to 42 degrees is 138 degrees
180-89= 91 degrees
If it is a complementary angle, the missing angle is 52 degrees. If it is a supplementary angle, the missing angle is 142 degrees. If it is an opposite angle, the missing angle is 38 degrees. Obviously, you need to know what type of angle you're looking for.
The answer depends on what the angle is missing from!

The complement of 89 degrees is: 89+1 = 90 degrees which is a complementary angle

180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
