solve it pls and explain it in details do not spam....​

Answer 1

Answer:

The correct option is C. 30°

Step-by-step explanation:

2sin2 θ=√3

sin2θ=√3/2

[since sin 60 = √3/2]

Thus,

sin2θ=sin60°

2θ=60°

θ=60°/2

θ=30°

Answer 2

Answer:-

• (c) is the correct option

Step-by-step explanation:

Given : 2 sin 2θ = √3

To find : Value of θ

Solution :

2 sin 2θ = √3

sin 2θ = √3/2

We know that value of sin A is √3 / 2 on A at 60°, so the value of 2θ is 60°

2θ = 60°

θ = 60°/2

θ = 30°

Required value of θ is 30°

Additional information :-

• sin 0° = 0

• sin 30° = 1/2

• sin 45° = 1/√2

• sin 60° = √3/2

• sin 90° = 1

• cos 0° = 1

• cos 30° = √3/2

• cos 45° = 1/√2

• cos 60° = 1/2

• cos 90° = 0
