Answer:
a. 11.3 units
b. 46.031°
c. 11.3 units
d. 46.03°
Explanation:
a. magnitude
B = [tex]\sqrt{R^{2}-A^{2} }[/tex]
= â15.7² - 10.9²
= â127.68
= 11.3 units
b. direction
θ = cosâťÂš(10.9units/15.7 units)
= 46.031â° north of west
c. thge magnitude at 15.7 units is the same as solution a above
15.7² = 10.9² + B²
B = 11.3 units.
d. the direction is same as  answer b.
θ = 46.031°
but the vector faces south of west
