Question

In the following figure ABCD is a parallelogram, find the value of x ,y and z.​

Answer 1

Answer:

x=60

y=60 (alternate interior angles)

z=110

Answer 2

Answer:

(angle 50,70 and x supplementry to each other , means it's sum is 180⁰)

angle 50⁰+x+70⁰=180

120+x=180

x=180-120

x=60⁰

angle x=y(alternate interior angle)

y=60⁰

(50+x)+z=180⁰

sum property of interior angle of parallelogram

(50+60)+z=180

110⁰+z=180⁰

z=180-110

z=70⁰
