Question

​

Answer 1

Answer:

Step-by-step explanation:

The value is x+y = 180.

Step-by-step explanation:

A circle creates an angle of 360 degree in its center.

Hence, the diameter divides the circle into two equal parts. The diameter creates an angle of 180 degree in its center.

The line ABC will be a straight line if the angle ABC will be 180 degree.

Hence, the value of x+y have to be 180 degree.

If we take ABC as the x axis and x=y=90 degree, then BD will be y-axis.
