(e19q6) angle *

[tamiatha]

sketch the angle with measure -2pi/3 radians
label its reference angle

i hane no work to show
i do not know how to do this
thanks

They were supposed to have covered this, in class and in the book, before homework was assigned on it! :shock:

To learn about reference angles and the unit circle, try some online lessons, such as this one. :wink:

Re: (e19q6) angle

Stapel, provided you with massive help.For me what I do for the first part of your question is :

For, ? ----> 180
2?/3 -----> ??

I usually decompose: (2?/3)(180)/(?)
.
.
.
Simplify : (2)(60) = 120 degrees

but since its -2?/3 , You actually graph it in anti-clock wise

The reference angle is 180-120=60 degress
