Answer:
to find the direction and resultant of this 3 vectors, lets solve this by components;
@ x y
1.25 + 0 +1.25
4.4 + 4.4 +0
3.6 -2.55 +2.55; for x comp..use =-3.6cos45; for y=3.6sin45
Total 1.85 3.8
finding the resultant = √ 1.85² + 3.8²;
=√17.87;
=4.2 miles;
direction = tan^-1 3.8/ 1.85;
direction(β ) = 64°;
=4.2miles @ 64° vector angle in the first quadrant at point ( 1.85 , 3.8 )
