Let's solve ~

x and y are values that represent the angle made by respective arcs on centre of the circle

that is :

  • x = 20°

Here, Angle x + Angle z = 180°

[ because they form linear pair ]

  • z + x = 180

  • z = 180 - x

  • z = 180 - 20

  • z = 160°

Now, we can observe that angle made by Arc Y is equal to :

  • y = z + x = 160° + 20° = 180°
