The ratio of the length of a vertical rod and the length of its shadow is 1: Find the angle of elevation of the sun at that moment?​

Answer»

30 degreeStep-by-step EXPLANATION:GIVEN :-l(BC)l(AB) = 3 1 now, angle of elevation, ∠ACB=θnow, tanθ=tan(∠ACB)= BCAB = 3 1 ⇒tan θ=( 3 1 )=tanθ=(tan 6π )⇒θ= 6π ∴ The angle of elevation = 6π =30 degree
