Calculating the resultant force using vector

[SumDumKid]

Please HELP!

I need help with a question...I don't know how to do it...can someone please tell me how.
This question is about calculating the resultant force using vectors.

Question:
There is a parachutist with a 500 N force acting upwards on him and a 1000 N force acting downwards on him. There is also a 300 N force of wind acting towards him at a 45 degree angle. How do I calculate the resultant force on the parachutist?

thank you for your time

So you have:

Forces in Y:
500N, 1000N

The force that act at a certain degree should be expressed in Y and X components:
If the wind of 300 N comes from below at 45 degree angle:

X component of the 300 N force: 300 x cos (45) = xxx N
Y component of the 300 N force: 300 x sin (45) = xxx N


to calculate the resultants of all forces use pythagoras
