Problem

The magnitude of v¡ú is 7, and its direction angle is 30¡ã.
The magnitude of w¡ú is 4, and its direction angle is 140¡ã.
Find the component form of v¡ú+w¡ú.
It's okay to round your intermediate calculations and final answer to the nearest hundredth.
v¡ú+w¡ú¡Ö( 
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
