Q. 2 C3.5( 19 Votes )
Choose the right option and justify your choice -
C) 
A. cos 60°
B. sin 60°
C. tan 60°
D. sin 30°
Answer :
We know that,
tan 30° = 1/√3
So, using this value of tangent, we can write
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
And we know, tan 60° = √3
But, cos 60° = 1/2
sin 60° = √3/2
& sin 30° = 1/2
Thus, option (C) is correct.
