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

-3x^2 plus 24x = 27 <br> complete the square

Rudik [331]

You can divide the whole expression by -3:

$-3x^2+24x=27 \iff x^2-8x = -9$

Recalling that

$(x-a)^2=x^2-2ax+a^2$

Let's compare the middle term:

$-8x = -2ax \iff a=4$

So, we want to complete

$(x-4)^2 = x^2-8x+16$

Which differs from $x^2-8x$ by 16. So, if we add 16 to both sides, we have

$x^2-8x=-9 \iff x^2-8x+16=7 \iff (x-4)^2=7$
