[tex]\star\sf \overrightarrow{A}=4N[/tex]

[tex]\star\sf\overrightarrow{B}=6N[/tex]

Angle=160

[tex]\boxed{\sf R=\sqrt{A^2+B^2+2ABcos\theta}}[/tex]

[tex]\\ \sf\longmapsto R=\sqrt{4^2+6^2+2(4)(6)cos160}[/tex]

[tex]\\ \sf\longmapsto R=\sqrt{16+36+48(-0.93)}[/tex]

[tex]\\ \sf\longmapsto R=\sqrt{52-44.6}[/tex]

[tex]\\ \sf\longmapsto R=\sqrt{7.4}[/tex]

[tex]\\ \sf\longmapsto R=2.7N[/tex]
