If the sin 90° is 1, then the cos ____ °= _____

lorasvet [3.4K]

That sentence is confusing...

That sentence is confusing...
There is no logical relationship between the prepositions.
You can put any angle and its cosine there.
You can put, for example:

Cos(90)=0 or Cos(0)=1... Both are correct options...

If your teacher wrote that, he doesn't know to write very good...

Good luck!

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{x^2 - 10x - 24}{x^2 - 3x - 108}$

Step 2: Simplify

[Fraction] Factor numerator: $\displaystyle \frac{(x - 12)(x + 2)}{x^2 - 3x - 108}$
[Fraction] Factor denominator: $\displaystyle \frac{(x - 12)(x + 2)}{(x - 12)(x + 9)}$
[Fraction] Divide: $\displaystyle \frac{x + 2}{x + 9}$

We know that x cannot equal -9 because we would get a divide by 0 (undefined) error. We also know that x cannot equal 12 because it was canceled out when simplifying.
