Step-by-step explanation:
Given the vector
v = 6i + 2√3j
The Magnitude of a vector:




![\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Aradical%5C%3Arule%7D%3A%5Cquad%20%5Csqrt%5Bn%5D%7Bab%7D%3D%5Csqrt%5Bn%5D%7Ba%7D%5Csqrt%5Bn%5D%7Bb%7D)


The Direction of a vector:
tan Ф = y/x
y=2√3
x = 6
tan Ф = y/x
= 2√3 / 6
= √3 / 3


Turning clockwise means the number increase, and counterclockwise means the number decreases
Therefore your answer is 37 + (3*1/2)-(3*1/4)
= 37.75
Hope this helped :)
