The value of KN in the circle O with diameter MN and radius OK is about 21.33 units.
A circle is the locus of a point such that its distance from a fixed point (center) is always constant.
Pythagoras theorem shows the relationship between the sides of a right angled triangle.
In the circle O, ∠MKN = 90° (angle from diameter), hence:
MN² = KM² + KN²
36² = 29² + KN²
KN = 21.33
The value of KN in the circle O is about 21.33 units.
