Keita left camp three days ago on a journey into the jungle. The three days of his journey can be described by displacement (distance and direction) vectors $\purple{\vec{d_1}}$, $\blue{\vec{d_2}}$, and $\green{\vec{d_3}}$.
$\quad$$\purple{\vec{d_1}} = (7,8)$
$\quad$$\blue{\vec{d_2}} = (6,2)$
$\quad$$\green{\vec{d_3}} = (2,9)$
$\quad$(Distances are given in kilometers, $\text{km}$.)
**How far is Keita from camp at the end of day three?**
[[☃ math-keypad 1]]$\,\text{km}$
(Round your final answer to the nearest tenth.)
**What direction is Keita from camp at the end of day three? Assume $0^\circ$ is the rightward direction.**
[[☃ math-keypad 2]]$^\circ$
(Round your final answer to the nearest degree. Your answer should be between $0$ and $180^\circ$.)
