Question

Fig. BEST is a parallelogram. Find the values x, y and z b=100​

Answer 1

Step-by-step explanation:

given ABCD is a //gm in which Angle B=100°

fing remaining angles

angle A+angle B=180°(co -int oppo . angle )

angle A+100°=180°

angle A=80°

angle A=angle C(oppo angle of //gm are equal )

OR

we can say that AB=CD(parallel side of //gm are equal )

so angle A=Angle C=80°

angle B=angle D(oppo angle of //gm are equal )

or we can say that AD=BC

so angle B= angle D
