Mark it as brainlist answer

Step-by-step explanation:

Cosec x = 1 / sin x. Hence, Cosec 60° = 1 / Sin 60° = 1 / (√3/2) ( Since, Sin 60° = √3/2) = 2/√3.

Sec x = 1 / Cos x. Hence, Sec 60° = 1 / Cos 60° = 1/(1/2) ( Since, Cos 60° = 1/2) = 2.

Cot x = Cos x / Sin x. Hence, Cot 60° = Cos 60°/ Sin 60° = (1/2) / (√3/2) = 1/√3.
