Answer 1

$\huge\boxed{\fcolorbox{red}{yellow}{Shailesh}}$

The angle of elevation is 30 degree

Tan theeta=opp.s/adj.s=h/root 3h=1/ root3

Tan 30 = 1/root3

Answer 2

Answer:

angle of elevation is 30°

Step-by-step explanation:

let AB be the shadow &AC be the tower&£be the angle of elevation

now ang(ABC)=90 because hieght is perpendicular to ground

so tan£=AC/AB

=h/√3h

=1/√3

= tan30°

so £=30°
