Answer 1

Answer:

The value of x+y in order to meet this condition is 180°.

Step-by-step explanation:

Attached figure shows ABC as a straight line.

The total angle at point B is 180°.  This condition will only meet when Angle x and Angle y are supplementary to each other.

Therefore, the value of x+y in order to meet this condition is 180°.
