Since AOC is a straight line, it measures at an 180 degree angle. This means that the angles on the line have to add up to 180.

Therefore, we could do 5y + 30 = 180 (Adding all the angles: y + 4y)

We would then solve it as a two-step equation

5y + 30 = 180

1. + 30 - 30 = 0

2. 180 - 30 = 150

3.
5y divided by 5 = y
150 divided by 5 = 30

y = 30

All in all, the value of y is 30. We can also check our work by substituting in the value of y

30 + 30 + 4(30) = 180

30 + 30 + 120 = 180

This equation is true so therefore, the value of y is 30.

Answer:

30°

Step-by-step explanation:

y+30° +4y =180° (angles on a straight line equal 180°)

5y+30° =180°

5y= 180° - 30°

5y = 150°

divide both sides by 5

5y/5 = 150/5

y= 30°
