Question

Am i correct?
The co-terminal angles of 25degrees is: 385, and 335.
The co-terminal angles of 180 is: 540 and -180
The co-terminal angles of -120 is: 240 and -480

Answer 1

Looks correct to me. Coterminal angles are calculated by adding or subtracting 360 degrees or 2pi (depending on degrees or radians) a certain number of times to find a new angle.

Answer 2

So they are all correct right?

Answer 3

how is 335 coterminal with 25?

Answer 4

I don't think 335 is co-terminal

Answer 5

I don't think these are all correct either

Answer 6

we find coterminal of 25 by:

25+360
and by
25-360

Answer 7

so coterminals, 25, 335, and 385

Answer 8

the other one is -335 sorry

Answer 9

25-360=-335

Answer 10

-335 is correct

Answer 11

ok:) and the other ones are ok?

Answer 12

And everything else is now correct

Answer 13

yes

Answer 14

ok great thank you guys!:)

Answer 15

before you leave, how do i determine if -105 and -465 and coterminals?

Answer 16

To find if an angle is co-terminal with another angle, you should be able to either add or subtract 360 to get that angle.

Answer 17

Can you exaplain it to me without giving me the answer? Id like to solve it first

Answer 18

I just did

Answer 19

oh ok il try

Answer 20

Yes they are coterminals right?

Answer 21

Correct

Answer 22

Great! thanks HEro!!

Answer 23

I never give the answer first. So anytime you want help without someone blurting the answer out, consult me :)
