It is a right angle, or an angle whose measure is 90 degrees or pi/2 radians.
The 3 angles of a triangle always add up to 180 degrees. You have 110 and 43, so that is 153 degrees. Subtract 153 from 180, and that is the remaining angle.
A reflex angle is one whose measure is greater than 180 degrees but less than 360 degrees. Vertical angles can be reflexive.
An angle of 43 degrees cannot be a vertical angle. A vertical angle, by definition, is 90 degrees
An angle of 43 degrees is an acute angle because it is greater than 0 but less than 90 degrees
A 43 degree angle would be called an "acute" angle. This is because its degrees do not exceed 90 which is a right angle. Anything above 90 would be an "obtuse" angle.
