Given:
- tan (2 × θ) = cot (θ + 6)
To Find:
- Value of theta (θ) = ?
Formula Used:
- cot θ = tan (90 - θ)
Solution:
Placing values,
➙ cot ( 90 - 2θ ) = cot (θ + 6)
➙ 90 - 2θ = θ + 6
➙ 90 - 6 = 2θ + θ
➙ 84 = 3θ
➙ θ = 84/3
➛ θ = 28.
Hence,
- Value of θ is 28.
ExtraShots:
- sin θ = cos (90 - θ)
- cos θ = sin (90 - θ)
- tan θ = cot (90 - θ)
- cot θ = tan (90 - θ)
- sec θ = cosec (90 - θ)
- cosec θ = sec (90 - θ)
