Question

Find x in a parallelogram PQRS if P=x , Q=x-20​

Answer 1

Angle P + Angle Q = 180° [Property of parallelogram]
Angle P = 3x° - 5°
Angle Q = 2x° + 15°
3x° - 5° + 2x° + 15° = 180° [ Putting value of Angle P and Angle Q]
5x° + 10° = 180°
5x° = 180° - 10°
5x° = 170°
x° = 170°/5
x° = 34°

X = 34

Answer 2

Answer:

100

Step-by-step explanation:

since in case of parallelogram P+Q=180

then x+x-20=180

give 2x=200

x=100
