Final answer:
In the given diagram, we can deduce that angle K is a right angle.
Step-by-step explanation:
In the diagram, since KN bisects JKM and JKM forms a right angle, we can deduce that the angle at K is also a right angle.
This is because if KN bisects JKM, it divides the angle into two equal halves. And since JKM is a right angle, each half of the angle must also be a right angle.
Therefore, angle K is a right angle.
