Question

in a parallelogram out of the two adjacent angles, one angle is greater than the other by 20 degree. find the measure of all angles.​

Answer 1

Let one angle =X+ 20°

Let the another angle =X

In parallelogram  opposite angle are equal,

In parallelogram adjacent angles are supplementary,

Angle sum property of a parallelogram =360°

X+20+X+20+X+X=360

4X+40=360

4X=360-40

4X= 320

X=320/4

x =  80

Angles are 80°,80°,

then x + 20 = 80 +20 = 100° , 100°
