Which list shows these numbers in order from least to greatest

B) -5, -2.4, 20%, sqrt(9), 3pi

Step-by-step explanation:

sqrt(9) = 3

3pi = 3 * 3.14 = 9.42

20% = 0.2

B) -5, -2.4, 20%, sqrt(9), 3pi

i think it is "b" but im not 100% sure because im learning this right now too. i hope this helped :)

They are complementary angles, or answer (B).

Complementary angles add up to 90 degrees. In the figure, angles a and b are part of a right angle (denoted by the little square thing).

So, a and b are complementary.
