Question

Cx = -105 m and Cy = -88.2 mFind the direction of the vector.

Answer 1

In order to find the direction we can use the next formula

$\tan (\theta)=\frac{Cy}{Cx}$

we are looking for theta therefore we need to isolate it

$\theta=\tan ^{-1}(\frac{Cy}{Cx})=\tan ^{-1}(\frac{-88.2}{-105})=40.03$

then because both components are negative me need to add 180 in order to find the direction of the vector

$\text{direction}=40.03+180=220.03\text{\degree}$
