Perform the operation and leave the result in trigonometric

Perform the operation and leave the result in trigonometric form. (Enter your angles in degrees between 0° and 360°.)

[2/3 (cos 140 degrees + isin 140 degrees)][4/5(cos 230 degrees + i sin 230 degrees)]

[2/3 (cos 140 degrees + isin 140 degrees) ]/ [4/5(cos 230 degrees + i sin 230 degrees)]

2 / 3 / 4 /5 [ cos ( 140 - 230 + 360 ) + i sin ( 140 - 230 + 360 ) ]

5 / 6 [ cos ( 270 ) + i sin ( 270 ) ]

trigonometric form is

5/6 [ cos 270 degrees + i sin 270 degrees ]
