a) magnitude:
b) direction (in degrees):

R = 500(cos20° , sin20°) + 200(cos135° , sin135°)
= ......

let me know what you get
Answered by ghost
i got
(469.84,171.01) + ((-141.42),141.42).
is this correct?
Answered by Reiny
correct so far.
Why did you not finish it?
You had asked for the magnitude and direction.
Answered by ghost
my final answers are:
329.42, 412.42
i did: 469.84+(-141.42)=329.42
i did: 171.01+141.42 = 412.42
Answered by Reiny
first of all, I got
(328.42 , 312.43) as the resultant vector, still not done

NOW, find the magnitude and direction of that.
Answered by ghost
the magnitude is 640.85, but how do i get the direction
Answered by ghost
hello?
i am still waiting for response!!
Answered by Reiny
tanø = rise/run = 312.43/328.42
ø = tan^-1 (.95130..)
= 43.57°

btw, your magnitude is wrong
magn = √(328.42^2 + 312.43^2) = 453.29
