Two horses on opposite sides of a narrow stream are pulling a barge along the stream. Each horse pulls with a force of 720N. The ropes from the horses meet at a common point on the front of the barge. What is the resultant force exerted by the two horses if the angle between the rope is 60o?

ANS= 1.25 x 103N (I also don't understand why the answer is written like this..)

I tried breaking it up into components but it didn't work out.. any advice would be great!

Thank you in advance.

Is the result perhaps 1,25*10^{3}
 
isn't 1247.1N?

Yes, the same result I get, but it's probably rounded to 1250, i.e. 1,25*10^3.
 
Ohhh okay, I didn't think of that, thank you all for your help!
 
You didn't get an answer yet?

Yes, the previous posts helped solve it. I had the answer to start with but because of how the answer key showed the answer I didn't think mine was right.
