If sin θ = 5/6 , what are the values of cos θ and tan θ?

For the answer to the question above, I'll provide a solution to my answer below
sin²θ + cos²θ = 1 

so, cos²θ = 1 - (5/6)² => 11/36 

=> cosθ = ±√11/6 

Also, tanθ = sinθ/cosθ => (5/6)/(±√11/6) 

i.e. tanθ = ±5/√11 
I hope my answer helped you. Feel free to ask more questions. Have a nice day!

The answer would be b
