Question

b. In a parallelogram ABCD if angle DAB = 75°
and angle DBC = 60°, find angle CDB and angle ADB.​

Answer 1

Answer:

Step-by-step explanation:

In a parallelogram sum of adjecent sides are equal to 180°

So,angleDAB+ADC=180°

75+ADC=180°

ADC=180-75

ADC=105°

AngleDBC=AngleADB (Alternate interior angle)

So,angleADB=60°

AngleADC=AngleADB+AngleCDB

105°=60°+AngleCDB

105°-60°=AngleCDB

55°=AngleCDB
