Answer:

(1+ sin¢ ) (1 - sin¢ ) = 7/23

Step-by-step explanation:

Given :- Tan¢ = 4/√7 = perpendicular (p) /base (b)

hypotenuse "h" = √p²+b² = √ 4²+(√7)² = √16+7 = √23

  • ∵ (1+sin¢) (1-sin¢) = 1-sin²¢ = cos²¢

  • cos²¢ = (base/hypotenuse)²= (√7)²/(√23)² = 7/ 23

∴ (1+sin¢)(1-sin¢) = 7/23Answer
