Question

for what value of x+y in given figure abc be a line? justify y axis answer.​

Answer 1

Answer:

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.

Answer 2

Answer:

the sum of x and y =180

Step-by-step explanation:

Diameter cuts circle into two parts which are equal
