Problem $04\mathrm{.}001-$ Finding angles and vectors with right triangles

The Cartesian components of a vector $\frac{?}{\text{b}\text{a}\text{r}}(B)$ are shown in the given figure. Find $,B_y,$ and $\frac{?}{\text{b}\text{a}\text{r}}(B),$ if $B_x=8\mathrm{.}0m$ and $=35.$

The value of $$ is

The value of $B_y$ is: $1.($Round the final answer to the nearest whole number.$)$

The value of $\frac{?}{\text{b}\text{a}\text{r}}(B)$ is : $($Round the final answer to four decimal places.$)$

$m.($Round the final answer to four decimal places.$)$
