Question

1) ABCD is a parallelogram. Find the value of x,y and z. ​

Answer 1

hey is your answer mate!!♢

100+x =180 (linear pair angles)

x =180-100

x = 80

x+y+30 = 180

80+y+30= 180

110+y=180

y=180-110

y=70

angle z=30 (alternate interior angles)

Answer 2

Hello. Here is ur answer :

z = 30 (vertically opposite angles)

x = 80 (as AC is straight line and 100+x=180, therefore x=80)

Sum of all sides of triangle = 180

SO,

x+y+30=180

(x=80)

then,

80+y+30=180

110+y=180

y=180-110

y = 70

THEREFORE

x = 80

y = 70

z = 30

Hope it helps :)
