ABCD is a parallelogram in which ∠DAB = 75° and ∠DBC = 60°, the measure of ∠CDB and ∠ADB is
  • a)
    ∠CDB = 30°, ∠ADB = 60°
  • b)
    ∠CDB = 45°, ∠ADB = 60°
  • c)
    ∠CDB = 75°, ∠ADB = 30°
  • d)
    ∠CDB = 40°, ∠ADB = 70°
Correct answer is option 'B'. Can you explain this answer?

Here in the question also it is mentioned that it is a parallelogram so we can get the answers by using parallelogram properties.
we know, opposite angles in llgm
so, DAB=DCB
DCB=55
Here if you see DCB is a triangle so angles sum will be equal to 180
so, DCB+DBC+BDC = 180
75+60+BDC = 180
135+BDC = 180
BDC= 180- 135
CDB= 45
Opposite sides will be parallel in a parallelogram
DA ll BC and BD transversal
so, ADB = DBC ( alternate interior angles )
ADB = 60
