Answer:
D (6)
Step-by-step explanation:
FIRST METHOD
1. Use vector analogy (If you learnt)
Consider WS as a vector
x component of WS is 5
y component of WS is 3
2. Plug in numbers (Pythagorean Theorem)
[tex]\sqrt{5^{2}+3^{2}}[/tex] ≈ 5.83
Nearest integer is 6
SECOND METHOD
1. Distance between two points formula
[tex]d (length) = \sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}[/tex]
W = (x1,y1) S = (x2,y2)
W = (-2,-1) S = (3,2)
2. Plug in numbers
[tex]d (length) = \sqrt{(-2-3)^{2}+(-1-2)^{2}}[/tex]
3. d ≈ 5.83
