Answer:
∠2=121°
Step-by-step explanation:
Ok, firts know that supplementary angles add up to 180 degrees, it means that ∠1+∠2=180°, and we are told that ∠1=4y+7 and ∠2=9y+4. <u>We need ∠2</u>.
∠1+∠2=180°
(4y+7)+(9y+4)=180 Solve the equation, finding y.
13y+11 = 180
y = (180-11)/13
y = 169/13
y = 13
Now we know y, ∠2=9(13)+4=121°

<em>Additional comment</em>
One of the "test-taking skills" that you need to learn is that <em>multiple-choice answers that make false statements can be immediately rejected</em>. (You don't even need to check to see if they answer the question.)
Of course, there are occasional questions that ask you to find the <em>false</em> statement on the list. In those cases, you reject the <em>true</em> ones.
