What is the value of y if x=30?

Improper question you need to provide more info or post a screenshot.

x=30° (given)

2y+2x=180° ( Supplementary angles )

2y+2×30 ∘ =180 ∘

2y+60∘ =180∘

2y=180−60

2y=120 ∘

⇒y=60 ∘

answerthe vertex form

step-by-step explanation:

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
