From what I could find, Sirens are asking for help. The song they sing is a cry for help. They are described as acting/singing like a "damsels in distress".
The answer would be 15.
The first equation would be ∠1 = 15°
Then the second equation is ∠2 = (3 * 15 + 30)° which simplifies to 75°
And since complementary angles need to equal 90° to be true we have to add both angles. So, ∠1 (= 15°) + ∠2 (= 75°) = 90°. Now that we know they equal 90°, 15 would be the answer to your problem.
Answer:
The correct answer would be "A". The specific reason for a piece of writing.
Explanation:
The purpose for a piece of writing can be defined as the intent, or the reason, for writing.
Hope this helps! :)
