Answer:

Step-by-step explanation:

$sin\theta =\frac{5}{13}\\ \\ \theta =sin^{-1}\frac{5}{13}\\ \\ \theta =22.62^o\\ \\ \\ a=90-22.62\\ \\ a=67.38^o\\ \\ \\ 13^2=5^2+x^2\\ \\ x^2=169-25\\ \\ x^2=144\\ \\ x=\sqrt{144}\\ \\ x=12$

-9 – 3.

Len [333]

Answer:

3 x -3y = -9y

3 x -1 = -3

The factored expression is 3(-3y - 1)

Step-by-step explanation:

All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.

The reason is because if you distributed the 3 it would become:

3 * -3y + 3 * -1 = -9y - 3
