To solve this, we are going to multiply our degrees by a conversion factor. Remember that 1°=
( \pi )/(180), so to convert -40° to radians, we are going to multiply -40° by the conversion factor
( \pi )/(180); that way we can cancel degrees and express our answer in radians:

(-40°)
(( \pi )/(180) )= -(2 \pi )/(9)

We can conclude that the correct answer is: B). -2π/9
