The quadrilateral shown is a rectangle. What is m∠MJN?
A) 24° B) 31° C) 66° D) 90°

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°
Thus,
∠MJN+∠KJN=90°
∠MJN = (90-24)°
∠MJN = 66°
Therefore, correct option is C.
