 \sf\color{pink} Given:-

  • AC = 15 m
  • ∠A = 60°
  • ∠C = 180°-(60°+90°) = 30°

\sf \color {red} To \: find:-

  • AB or height of wall.

\sf \color{green}Solution:-

\boxed{\purple {\rm{sin30 \degree \:  =  \frac{AB}{AC} =  \frac{ 1 }{2}}}}

\rm  \frac{AB}{AC}  =   \frac{ 1 }{2}

\rm  \frac{AB}{15}  =\frac{ 1 }{2}

\rm AB =  \frac{ 1 }{2}  \times 15

\rm{AB = 7.5}

\rm  {\underline{\underline{ \blue{AB = 7.5\: m}}}}

 \sin(30)° =  \frac{ᴀʙ}{ᴀᴄ}   =  \frac{1}{2}

 \frac{ᴀʙ}{ᴀᴄ} =  \frac{1}{2}

 \frac{ᴀʙ}{13} =  \frac{1}{2}

ᴀʙ =  \frac{1}{2}  \times 13

ᴀʙ = 7.5
