Question 1194154: Point p(-5,-8) is on the terminal arm of the angle ,θ, in standard position. Determine all the values of θ for -540 degrees ≤ θ ≤ 270 degrees
I found the principal angle of 238 degrees and the related acute angle of 58 degrees. Then I am stuck from there for the other values.

.
If 238 degrees is determined correctly (I did not check it), then all others are those that greater or lesser
than 238 by 360*n degrees, where n is any integer.
So, you should consider all the angle measures of this form 238 +/- 360n in the given interval.

Comment from student : this is the part that i dont get Determine all the values of θ for -540 degrees ≤ θ ≤ 270 degrees
the answers are : 238, -122 and -182.
My response : 238 - 360 = -122. Your value in your comment is correct.
238 - 720 = -482. Your value in your comment is not correct.
