Given :
⬤ Two adjacent angles of a Parallelogram are in the Ratio 3 : 2 .
To Find :
⬤ Measure of Each Angle of Parallelogram .
Solution :
Let :
- Measure of First adjacent angle be 3x.
- Measure of Second adjacent angle be 2x.
As we know that , Sum of all adjacent angles of a Parallelogram is 180 degree . Hence ,
5x = 180°
x = 180/5
x = 36°
Therefore , The Value of x is 36 degree .
Hence ,
Measure of First adjacent angle = 3x
= 3(36)
= 108°
Measure of Second adjacent angle = 2x
= 2(36)
= 72°
As Opposite angles of Parallelogram are equal . Therefore , Measure of Four adjacent angle are 108° , 72° , 108° and 72° .
Check :
3x + 2x = 180°
108 + 72 = 180°
180° = 180°
Hence Checked .
