Answer 1

Answer:

Hope this helps you...

Answer 2

Answer:

θ = 60°

Step-by-step explanation:

Given :

(cosθ)/(1 - cosθ) + (cosθ/1 + sinθ) = 4

⇒ cosθ(1 + sinθ) + cosθ(1 - sinθ)/ 1 - sin²θ = 4

⇒ (cosθ + cosθsinθ + cosθ - cosθsinθ)/1 - sin²θ = 4

⇒ (2 cosθ)/cos²θ = 4

⇒ (2/cosθ) = 4

⇒ cosθ = 1/2

⇒ cosθ = cos 60°

⇒ θ = 60°
