Question

what is the reference angle of 4? not four degrees just 4.

Answer 1

4 radians?

Answer 2

i'm not sure. maybe.

Answer 3

well if you aren't sure, then idk because I'd have to see the book to see what they want

Answer 4

it says Below, express θ′ in the same units (degrees or radians) as θ. The reference angle of 4 is ___________

Answer 5

I'm guessing there's a picture?

Answer 6

nope

Answer 7

hmm then idk what they want. If it's just 4 degrees, then the answer is 4 degrees because you're in Q1

Answer 8

4 radians, you have to multiply by 180/pi to convert to degrees

Answer 9

this is the exact question if you want to take a look

Answer 10

my the red answer was incorrect

Answer 11

how did you get that 49 answer

Answer 12

this is probably a completely wrong approach but i multiplied 4 by 180/pi becuase that's how you convert radians to degrees and then subtracted that answer from 180. It was just a guess.

Answer 13

*because

Answer 14

that seems to work if 4 refers to 4 radians

Answer 15

why not try to plug in the formula in terms of pi

Answer 16

in other words, instead of type the approximation, type in the expression in terms of pi right before you got that approximation

Answer 17

do you mean like 720pi - 180? it says that's wrong too :(

Answer 18

ok, do NOT convert to degrees

then find the reference angle in terms of radians

Answer 19

leave the answer in terms of pi

Answer 20

4 radians is in Q3 because 4 radians is approximately 229 degrees (between 180 degrees and 270 degrees)

Answer 21

so if 4 radians is equal to pi/45 i would subtract that from pi?

Answer 22

ugh it says that that's wrong too

Answer 23

no you're overthinking

Answer 24

think of how to find the reference angle in degree mode (in Q3)

Answer 25

apply that idea to radian mode
