30 . what is the ratio between length of vertical rod & the length of its shadow
​

Answer 1

Answer : Given :-

Given :-l(BC)l(AB)=31

Given :-l(BC)l(AB)=31now, angle of elevation, ∠ACB=θ

Given :-l(BC)l(AB)=31now, angle of elevation, ∠ACB=θnow, tanθ=tan(∠ACB)=BCAB=31

Given :-l(BC)l(AB)=31now, angle of elevation, ∠ACB=θnow, tanθ=tan(∠ACB)=BCAB=31⇒tanθ=(31)

Given :-l(BC)l(AB)=31now, angle of elevation, ∠ACB=θnow, tanθ=tan(∠ACB)=BCAB=31⇒tanθ=(31)=tanθ=(tan6π)

Given :-l(BC)l(AB)=31now, angle of elevation, ∠ACB=θnow, tanθ=tan(∠ACB)=BCAB=31⇒tanθ=(31)=tanθ=(tan6π)⇒θ=6π

Given :-l(BC)l(AB)=31now, angle of elevation, ∠ACB=θnow, tanθ=tan(∠ACB)=BCAB=31⇒tanθ=(31)=tanθ=(tan6π)⇒θ=6π∴ The angle of elevation =6π=30∘
