Question

Find the reference angle for the given angle.

-404°

A. 44°

B. 46°

C. 134°

D. 136°

Answer 1

i guess you are supposed to add 360 repeatedly until you get a number larger than zero

Answer 2

i tried it. doesnt work. u get -44, then 316..

Answer 3

oh then i guess i do not know what a "reference angle" is
sorry

Answer 4

-404 is coterminal to 316

Answer 5

316 is larger than 270 and less than 360, so its in the 4th quadrant

Answer 6

which means that the reference angle is

360 - 316 = 44

Answer 7

the rule is:

if the angle x is in quadrant IV, then the reference angle y is

y = 360-x

Answer 8

ok thank u so much!
