Question

In the adjoining figure , ABCD is a parallelogram. find X,y,z and w​

Answer 1

1) X+90+20=180......(sum of all angles)

X+110=180

X=180-110

X=70

2)

Angle A+Angle B= 180.....(adjacent angles of parallelogram are supplimenty)

X+Z=180

70+Z=180

Z=180-70

Z=110

3)

angleA=angleC..... opposite Angeles of a parallelogram

angle c=X

angle c=70

y+70+90=180

y+160=180

y=180-160

y=20

4)

angle B=angle D... opposite Angeles

Z=angle D

angle D=110

w+y+20=110

w+20+20=110

w=110-20-20

w=90-20

w=70

the value of X,y,z and w are 70,20,110 and 70
