Answer:
Citizens
Explanation:
This is a very strange question without context. In the first democracy, if we take it to be Athenian democracy, then it would be citizens. please note that only men could be citizens and women, slaves, etc were excluded from citizenship status.
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.
