f2= 25sin30 +25cos30

f3= +12sin290 12cos30

find each of these values but you can only add cosines with cosines and sines with sines, but then with those values you will need to find the magnitude and the angle of the values

in case that doesnt make sense.

[(40cos90+25cos30+12COS290)^2 +

(40sin90+25sin30+12sin290)^2]^(1/2)

thats what you need to do...remember this for physics
