Evaluate :

sin 18°/cos 72°

find the value and plizzzskqdnwk

Dear Student

sin 18°/cos 72°
To simplify this,
convert the sin function into cos function
We know that,
18° is written as 90° - 72°,
sin 18°= cos 72°.
= sin (90° - 18°) /cos 72°
Substitute the value, to simplify this equation
= cos 72° /cos 72°
= 1

Thanks
