Explanation:

Step1: Add x - components

Add the x - components of vectors $\mathbf{u}$ and $\mathbf{v}$. The x - component of $\mathbf{u}$ is - 6 and of $\mathbf{v}$ is - 2. So, $-6+( - 2)=-6 - 2=-8$.

Step2: Add y - components

Add the y - components of vectors $\mathbf{u}$ and $\mathbf{v}$. The y - component of $\mathbf{u}$ is - 7 and of $\mathbf{v}$ is - 7. So, $-7+( - 7)=-7 - 7=-14$.

Answer:

$\langle - 8,-14
angle$
