Thank you very much hansthegerman and redbelly98, I really do appreciate the help

what if its more of a square? like this http://tinypic.com/r/53k6ro/7 do you make it into a square and draw the resultant and measure?

so if i have 9.5 & 5.5 how do i find the resultant? I completely forgot over this summer

ohh! I remember learning this in trig last year! but, how do i do this when I don't know how long each side is?

so it looks like a triangle? Like this? http://tinypic.com/r/163n7n/7

http://tinypic.com/r/2gsfm37/7" I would show work, but I am not sure how to even approach this, please help! Thank you!

I did that, i did sin -1 (2/4) and i got .5235987756 , but i don't know how to use that to get an answer

So then how would I use trig?

Sorry to bother again, I tried approaching this by finding the other leg (through Pythagorean Theorem) and got 3.46. Then I did a proportion, 90 / 4.0 = x / 3.46 , but I couldn't get an appropriate answer.

so 180.27 / .75 = 240.36? Am i approaching this correctly?

oh! okay yeah so then 200 seconds? right? Or would you take the 180.27 / .75 ? sorry if I keep dragging this I just want to be sure I got this

So then how do I figure that out? He went across 100 m north then 150 m across, how do I figure out how long it took him? 150 / .75 which is 200 seconds?

It doesn't say, but I guess I could do the following: 250 / .75 which is 333.33 seconds.. ?

1. A man points his rowboat north from A to B, straight across a river of width 100 m. The river flows due east. The man starts across, rowing steadily at 0.75 m/s and reaches the other side of the river at point C, 150 m downstream from his starting point. What is the speed of the river...

Thank you very much!
