Question

What is complementary in math terms

Answer 1

geometry right?

Answer 2

I think @helpmenowplease

Answer 3

ok in angle measurement you have two main points 90 degrees and 180 degrees
complementary means that those two or more angles will add up to 90 degrees

Answer 4

and supplementary will add up to 180

Answer 5

do you have an actual problem assigned to you that might help you also if i walk you through it

Answer 6

ok

Answer 19

Find the probability of each event then describe the complementary event of each event.

Answer 20

from 1-30

Answer 21

1. P (12)
2. P (odd)
3. P (digit )
4. P (integer)
5. P (less than 1)
6. P (greater that 18)

Answer 22

...ok i honestly have no idea what this is talking about
@dpaInc @milliex51 Any ideas?

Answer 23

what do you mean by "this"

Answer 24

this problem
when cutecats said complementary i thought she was meaning the geometry term, an i have no idea what to do with this problem

Answer 25

complementary event is like the "opposite" event

Answer 26

what?

Answer 27

complementary angles add up to 90 degrees, supplementary = 180 degrees

Answer 28

1. P (-12)
2. P (even)
3. P (letter )
4. P (non integer (any fraction))
5. P (greater than 1)
6. P (less that 18)

Answer 29

@cutecats , those are probability questions you posed... what is the context for those questions?

Answer 30

what?

Answer 31

Just to clear things up, complementary has two basic meanings in math


In geometry, two angles are complementary when they add to 90 degrees.

Ex: a 30 degree and a 60 degree angle are complementary angles since 30+60 = 90


In probability, two events are complementary when their probabilities add to 1

Ex: the events of flipping heads and tails have probabilities of 1/2 and 1/2. So they are complementary events since 1/2 + 1/2 = 1
