Zero. For example, if two people pull in the same direction, they are more effective than if they pull in opposite directions. The latter (180°) is the worst-case scenario in this case.

It is a reflex angle because it is greater than 180 degrees.
As long as the sides correspond then yes. The other three are: Side-Side-Side Side-Angle-Side - the angle *MUST* be between the two sides Right angle-Hypotenuse-Side
The clear difference between positive and negative rake angles is that for the positive rake angle,the leading edge of the cutting tool is behind the perpendicular of the material to be cut.While the tool leading edge is ahead or beyond the perpendicular for the negative rake angle.
The direction will change; the magnitude of the resultant force will be less.

using parallelogram principle. 15.5N
If the angle decreases, the magnitude of the resultant vector increases.
-- When forces of unequal magnitude are added, the magnitude of the sum can be anything between the difference and sum of the individual magnitudes, depending on the angle between them. -- When forces of equal magnitude are added, the magnitude of the sum can be anything between zero and double the individual magnitudes, depending on the angle between them.
The resultant (sum) of nonconcurrent forces is given by the Law of Cosines, which is the product of the vector sums and their conjugate: C^2 = (A + B)(A + B)*=(AA* + BB* + AB* + A*B)= (AA* + BB* + 2ABcos(AB)) The angle of C is given by sin (C) =A/C sin(AB) angle(C ) is smaller than the angle between A and B, angle(AB).
Zero degrees. This essentially adds up the forces.
Depending on the angle between them, those two forces can combine to producea resultant anywhere between 10N and 40N. The maximum of 40N occurs whenboth forces act in exactly the same direction.
Zero.
The question can only be answered if the MAGNITUDE of the resultant is equal to either. Although this is not stated, if that is the case, the answer is 60 degrees.
The resultant vector has maximum magnitude if the vectors act in concert. That is, if the angle between them is 0 radians (or degrees). The magnitude of the resultant is the sum of the magnitudes of the vectors.For two vectors, the resultant is a minimum if the vectors act in opposition, that is the angle between them is pi radians (180 degrees). In this case the resultant has a magnitude that is equal to the difference between the two vectors' magnitudes, and it acts in the direction of the larger vector.At all other angles, the resultant vector has intermediate magnitudes.
The resultant decreases from 0 degrees until the angle is 180 degrees and then increases until 360 degrees.
