Answer 5

sorry... dog unplugged computer :P

Answer 6

No problem. Do you want me to talk you through it, or just give you the answer?

Answer 7

ummm... can you give me the answer and then explain it please?
THANK YOU SO MUCH!!!!

Answer 8

Sure.
26.4N;51.8 degrees
First break the two down into their x and y components. Do this with the formula:
(r1 cos theta + r2 cos theta, r1 sin theta + r2 sin theta)
(14*cos(104)+21*cos(20),14*sin(104)+21*sin(20))
then you will have the (x,y) of the resultant vector.
(16.3466,20.7666)
to get the magnitude use the formula:
sqrt(x^2+y^2)
sqrt(16.3466^2+20.7666^2)
26.4N
to get the direction use this formula:
arctan(y/x)
arctan(20.7666/16.3466)
51.22 degrees
That is not exactly 51.8 degrees but it is really close, so we can chalk the discrepancy up to rounding differences.

Answer 9

Thank you very very very much :D

Answer 10

Do you understand all that?

Answer 11

yes :) and thank you for the formula for the first step... when i found a place that explained it, it didn't give the formula, it just said break it down into the x and y components. makes so much sense in ur explanation :D

Answer 12

Happy to be of assistance!
