Answer:
OK so the equation has a exponent so if there is a exponent then you need to multiply. since 227 is the Area and the exponent is 2.
Step-by-step explanation:
APZ is the correct answer
Basically the answer is 6, if you'd like an explanation, let me know. :)
<u>Answer and explanation</u>
(1+sinθ)(1-sinθ)=cos²θ
We are to prove that the left hand side is equal to the right hand side.
(1+sinθ)(1-sinθ) = 1(1-sinθ) + sinθ(1-sinθ)
= 1 - sinθ + sinθ - sin²θ
= 1 - sin²θ
From the trigonometric identity sin²θ + cos²θ = 1,
1 - sin²θ = cos²θ
