m<M + m<N = 180°
11x + 6x - 7 = 180
11x + 6x = 180 + 7
17x = 187
x = 187 : 17 = 11

m<M = m<O = 11x = 11 · 11 = 121°
m<N = m<L = 6x-7 = 6 · 11 -7 = 66 - 7 = 59°

Check : 121° + 59° = 180° OK !

Algebraically prove that X^3+10/x^3+9=1+ 1/x^3+9 where x is not equal to -3

Algebraically prove that X^3+10/x^3+9=1+ 1/x^3+9 where x is not equal to -3
 $\dfrac{x^3+10}{x^3+9}=1+\dfrac{1}{x^3+9} \\ \\ \\ \dfrac{x^3+10}{x^3+9}=\dfrac{(x^3+9)+1}{x^3+9}\\ \\ \\ \dfrac{x^3+10}{x^3+9}=\dfrac{x^3+10}{x^3+9} \\ \\ \\x\in R \qquad x\in (-\infty, +\infty)$

Answer:

$x=16 * cos(46)$

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

$cos (46^{o} ) = \frac{x}{16}$ (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

$x=16 * cos(46)$

Hope this helps!
