Question

A pole 6m high casts a shadow 2 root 3 metre long find the angle of elevation

Answer 1

$\tan \alpha = 6 \div 2 \sqrt{3} \\ = 3 \div \sqrt{3} \\ = \sqrt{3} \\ \tan\alpha = \sqrt{3} \\ \tan \alpha = \tan(60)$
therefore the angle of elevation is 60°

Answer 2

tan β = ab/bc

tan β = 6/2√3

tan β = 3*√3/3

β = √3

tan 60 degree
