Answer:

[tex]x = 600[/tex]

Step-by-step explanation:

Let's right our equation

[tex] \frac{x}{4} + 30 = 180[/tex]

This due to our straight angle

Subtract 30 from both sides

[tex] \frac{x}{4} = 150[/tex]

Multiply both sides by 4

[tex]x = 600[/tex]

Brainliest please :)
I believe x is 600 because it there is a straight line, 600/4 = 150 and 180-150 =30
