Find the resultant for the following directions.

20 degrees east of south for 1/2"

80 degrees South of west for 5"

15 degrees west of north for 1"

35 degrees North of East for 3"

40 degrees South of East for 1"

2. Relevant equations

R2 = a2 + b2

3. The attempt at a solution

i graphed the measurements with each 5" = 1/2" on graph paper. then i connected the tail of the first vector to the head of the end point and measured the resultant but when i calculated it i got 31.55, to calculate this i found the x,y for each vector. vector 1- 4.69,-1.71. vector 2- - and -8.68, -49.24. vector 3- -9.66, 2.59. vector 4- 24.57, 17.21, vector 5- 8.19, -5.74. i added up the totals for each x and y then used the resultant formula to get the resultant to be 31.55. is that correct?
