Question

Tower of height 30m casts a shadow of 10√3 then find the angle of elevation

Answer 1

let theta be the angle of elevation of sun.

tan theta = height of tower ÷ length of shadow

in this case tan theta = 30/10√3 = √3

since tan theta is √3 the theta is 60 degrees

therefore the angle of elevation is 60 degrees.

hope this will help you
