Answer 2

Step-by-step explanation:

Sinθ  =  BC/AC  &   Sin²θ  =  BC²/AC²  and Cosθ  =  AB/AC  &   Cos²θ  

right angled ∆ ABC

∠ABC = ∠B  = 90°

∠BAC = ∠A  = θ

AB = Base

BC = Perpendicular

AC = hypotenuse

Sinθ  =

Perpendicular / Hypotenuse

=> Sinθ  =  BC/AC

  Sin²θ  =  BC²/AC²

Cosθ  = Base / Hypoyenuse

Cos²θ  =  AB²/AC²
