[soyeb_jim]

I am new to latex. Can't figure out how to put a side text box. Here is an image of what i want to do. left one is done with ms word and right one with latex.

\begin{enumerate}[ wide=0em, label=\textenglish{\textbf{ \arabic* .}}, itemsep=0pt, parsep=1ex]
    \item ভেক্টরের লব্ধি $R=\sqrt{P^2+Q^2+2PQcos\alpha }$

    \item  লব্ধি $R$ ও কোনো ভেক্টর $P$ এর মধ্যবর্তী কোণ $\theta ={{\mathrm{tan}}^{-1} \left(\dfrac{Qsin\alpha }{P+Qcos\alpha }\right)\ }$
        
    \item  $\overrightarrow{P}$ ও $\overrightarrow{Q}$ এর লব্ধি $\overrightarrow{R}$ হলে, 
    \[\dfrac{P}{{\mathrm{sin} \beta \ }}=\dfrac{Q}{{\mathrm{sin} \alpha \ }}=\dfrac{R}{{\mathrm{sin} \left(\alpha +\beta \right)\ }}\] 

    \item  $A=A_x\hat{i}+A_y\hat{j}+A_z\hat{k}$ হলে $\left|A\right|=\sqrt{A^2_x+A^2_y+A^2_z}\ $ 

    \item  ডট গুনণ $\overrightarrow{A}\cdot \overrightarrow{B}=AB{\mathrm{cos} \theta }=A_xb_x+A_yb_y+A_zB_z$

    \item  তিনটি ভেক্টর একই তলে হবে যদি $\overrightarrow{A}\left(\overrightarrow{B}\times \overrightarrow{C}\right)=0$
