ground
then find the
long
on the​

Answer 1

Answer:

∴ Angle of elevation of sum is 60°.

Step-by-step explanation:

R.E.F image  

Given height of pole =6m

length of shadow =2√3m

Let 'θ ' be elevation. of sum then

tanθ = AB/BC = 6/2√3

tanθ =  √3

tanθ = tan  π/3

then θ =   π/3

∴ Angle of elevation of sum is 60°.
