  • In ∆FDE

[tex]\\ \sf\longmapsto tanF=\dfrac{3.6}{2.4}[/tex]

[tex]\\ \sf\longmapsto tanF=\dfrac{3}{2}[/tex]

[tex]\\ \sf\longmapsto tanF=1.5[/tex]

[tex]\\ \sf\longmapsto <F=tan^{-1}(1.5)[/tex]

[tex]\\ \sf\longmapsto <F=56.3°[/tex]

  • In ∆FHC

[tex]\\ \sf\longmapsto cosF=\dfrac{x}{3.2}[/tex]

[tex]\\ \sf\longmapsto x=3.2cos(56.3)[/tex]

[tex]\\ \sf\longmapsto x=3.2(0.5)[/tex]

[tex]\\ \sf\longmapsto x=1.6[/tex]
