It should be A

$$y + x + 30 = 180$$ (angles on a straight line)

$$y + 4y + 30 = 180$$

$$5y = 150$$

$$y = 30$$

Given, x = 4y

y + x + 30 = 180
5y = 150
y = 30

y+x+30=180
y+4y=150
5y=150
y=30

We see that the sum of x, y, and 30 is 180, and since x = 4y, we have:

4y + y + 30 = 180

5y = 150

y = 30
