Given the following forces : A : 50 N , 63 above the + axis ( positive is ) B : 65 N, 32 E of N C : SON , + y-axis ( positive y-anis ) D= FS N, 48 w of s The resultant was computed as 80 N, col" above the - (negative) a x aris. What will be the magnitude of the 5th vector . (use component method ) what will be the direction of the 5th force
