Answer:

1 - cosΘ

Step-by-step explanation:

using the identity

sin²x + cos²x = 1 , then

sin²x = 1 - cos²x

$\frac{sin^20}{1+cos0}$

= $\frac{1-cos^20}{1+cos0}$ ← factor 1 - cos²Θ as a difference of squares

= $\frac{(1-cos0)(1+cos0)}{1+cos0}$ ← cancel 1 + cosΘ on numerator/ denominator

= 1 - cosΘ
