is this a second post?

a radian is the size of a central angle of a circle that subtends a circumferential arc that is the length of the radius
in English ___ if you cut a piece of pie (not pi) and the outer arc of the crust is the same length as the radius of the pie
___ then the angle of the point of the piece is one radian
since the circumference of a circle is 2*pi*r; 360º (a whole circle) equals 2pi radians
in your case, -5pi/6 is a negative angle of ___ (-5pi / 6)(360º / 2pi) or -150º
