Question

2sin 2theta =√3 value of the theta​

Answer 1

Required Answer:-

Given:

• 2sin(2x) = √3

To find:

• The value of x.

Solution:

Given that,

➡ 2 sin(2x) = √3

➡ sin(2x) = √3/2

From Trigonometry Ratio Table,

➡ sin(2x) = sin(60°)

➡ 2x = 60°

➡ x = 60°/2

➡ x = 30°

Hence, the value of x is 30°

Answer:

• x = 30°

Verification:

Let us verify our result.

When x = 30°,

2 sin(2x)

= 2 sin(2 × 30°)

= 2 sin(60°)

= 2 × √3/2

= √3

Hence, our answer is correct (Verified)

Relationship between Trigo Functions:

• sin(x) = 1/cosec(x)
• cos(x) = 1/sec(x)
• tan(x) = 1/cot(x)
• sin(x)/cos(x) = tan(x)
