Question

find the value os x,y,z​

Answer 1

Answer:

x=40

y=140

z=40

Step-by-step explanation:

Since ABCD is a cyclic quad.

angle A+angle C=180

140+x=180

x=40

Now ABCD is a trapezium

AB||CD

angle A +angle D=180

140+z=180

z=40

and y+z=180(cyclic quad.)

y=140

mark as brainliest if I deserve it

Answer 2

Answer:

it is a cyclic quadrilateral.

so angle A + angle C=180 degrees.

so angle A+ x =180

140+x=180

x=40°

A+B+C+D= 360

(A+C=180)

180+z+y =360

z+y=180

[A+D,should be 180]

so Z= 40,so A+D becomes 180

And y =140.
