Question

In the given figure O is the centre of the circle. Show that x + y = z​

Answer 1

Step-by-step explanation:

angle y is 360- half of angle z and angle x =double half of angle z(by propery of circle that the angle substended by an arc of A circle at centre is double the angle substended by it at any point on remaining part of the circle)

Therefore, x+y=z
