Question

a ray stands on a line . if x=30°,then y equals to​

Answer 1

Answer:

So y is 150° if x and y are supplement of each other OR if they are in a linear pair... And Since only a Ray is Given.

Answer 2

Answer:y=150°

Step-by-step explanation:

If a ray stand on a line ,then the sum of two adjacent angles is equal to 180 degree.

So We can write this,

X+y=180°

=30°+y=180°

y=150°
