Answer 1

24 degrees

Explanation:

Supplementary angles add up to 180 degrees. So in order to find out what y is, you simple subtract the value of w from 180.

That would be 180-156= 24

y=24 degrees

Answer 2

`w=24`

Explanation:

Supplementary angles add up to 180°

Write an equation:

`w+y=180\\w+156=180\\w=24`
