Question

plzz.. answer this question...

Answer 1

Hey, mate the given quadilater is cyclic quadilater
=>
2x-y+x-2y=180.. {because sum of opposite angles of a cyclic quadilater is =180

2x+y=180...... equation 2

x-y=60...... equation 1


Now multiple equation 1 by 2

2x-2y=120.... equation 3
Now subtracting equation 3 by 1

-3y=-60

y=20
x=80
