**Reiny**, Tuesday, February 18, 2014 at 12:22amfirst vector = (530cos0, 530sin0

= (530,0)

2nd vector = (80cos220 , 80sin 220

= (-61.28355, -51.423

resultant = ((468.71644 , -51.423)

maginitude = √((468.71644^2 + (-51.423)^2 )

= 471.529

direction:

tan ฿ = -51.423/468.71644 = -.839..

฿ = E 40° S
