Question

If sin77°=x,than the value of tan 77°​

Answer 1

Answer:

We know that

We know thatcos2 θ + sin2 θ = 1

We know thatcos2 θ + sin2 θ = 1⇒ cos2 77° + sin2 77° = 1

We know thatcos2 θ + sin2 θ = 1⇒ cos2 77° + sin2 77° = 1⇒ cos 2 77° = 1 – sin2 77°

We know thatcos2 θ + sin2 θ = 1⇒ cos2 77° + sin2 77° = 1⇒ cos 2 77° = 1 – sin2 77°⇒ cos 77° = √(1 – sin2 77°)

We know thatcos2 θ + sin2 θ = 1⇒ cos2 77° + sin2 77° = 1⇒ cos 2 77° = 1 – sin2 77°⇒ cos 77° = √(1 – sin2 77°)And Given that sin 77° = x

We know thatcos2 θ + sin2 θ = 1⇒ cos2 77° + sin2 77° = 1⇒ cos 2 77° = 1 – sin2 77°⇒ cos 77° = √(1 – sin2 77°)And Given that sin 77° = x⇒ cos 77° = √(1 – x2 )
