Step-by-step explanation:

all the angles of the rectangle are right angle

therefore, angle MJK=90°

∠MJN+∠KJN=90°

∠MJN = (90-24)° = 66°

All angles of a rectangle is right angled or 90°.

C) 66°

Given:

∠KJN= 24°

Diagonals in a Rectangle:

  • The diagonals bisect each other but do not form right angles at the center.
  • They form linear pairs of angles, obtuse angle + acute angle, as at each of the diagonal.

Thus,

∠MJN+∠KJN=90°

∠MJN = (90-24)°

∠MJN = 66°

Therefore, correct option is C.
