lubasha [3.4K]

Answer:

Step-by-step explanation:

Given quadratic equation is,

-32 = 2(x² + 10x)

-32 + 50 = 2(x² + 10x + 25)

18 = 2(x + 5)²

9 = (x + 5)²

± 3 = (x + 5)

x = -2 or x = -8

If sinx is approximately 0.2588, what is the measurement of x to the nearest degree? Approximately, what is the cosine of the an

zavuch27 [327]

$\bf sin(x)\approx 0.2588\implies \measuredangle x \approx sin^{-1}(0.2588)\\\\
-----------------------------\\\\
sin\left(\frac{\pi}{2}-{{ \theta}}\right)=cos({{ \theta}})\qquad 
cos\left(\frac{\pi}{2}-{{ \theta}}\right)=sin({{ \theta}})\leftarrow 
\begin{array}{llll}
complementary\\
angles
\end{array}\\\\
-----------------------------\\\\
thus\qquad cos\left( \frac{\pi }{2}-x \right)=sin(x)\approx 0.2588$
