Question

in the given figure, ABCD is a parallelogram in which ∠BDA = 75 degree and ∠DBC =60 degree Calculate: ∠CDB.​

Answer 1

Answer:

45*

Step-by-step explanation:

Angle C =75*(opposite angle property)

Angle B =60*

Angle D = 180-(75*+60*)

= 180*- 135*

= 45*

Answer 2

∠ CDB = 45°

Step-by-step explanation:

In parallelogram ABCD

Let us assume ∠ DBA as ''∠ 1''

∠ CBA + ∠ DAB= 180° (sum of adjacent angles is 180°)

(60° + ∠ 1) + 75° = 180°

∠ 1 + 135° = 180°

∠ 1 = 180° - 135°

∠ 1 = 45°

Now, let us assume angle CDB as ''∠ 2''

∠ 1 = ∠ 2 (Alternate interior angles)

So, ∠ 2 = 45°
