1.	If →B makes an angle of 53∘ and →C makes an angle of 37∘ with x−axis as shown in the figure and the magnitude of →A and →C is equal to 10 and 5 respectively, then the magnitude of →B is [Given, →A+→B+→C=0] (Take √9804=99)
Answer» If $\to B$ makes an angle of $53^{\circ}$ and $\to C$ makes an angle of $37^{\circ}$ with $x -$ axis as shown in the figure and the magnitude of $\to A$ and $\to C$ is equal to $10$ and $5$ respectively, then the magnitude of $\to B$ is [Given, $\to A + \to B + \to C = 0$ ] (Take $\sqrt{9804} = 99)$
