Answer 1

Answer:

$w=24$

Step-by-step explanation:

Supplementary angles add up to 180°

Write an equation:

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

Answer 2

Answer:

24 degrees

Step-by-step 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
