Answer:

D. 3

Step-by-step explanation:

The sides with lengths 25 and 5 are corresponding, so their ratio is 25/5 = 5/1

The sides with lengths 18 - x and x are also in a 5 to 1 ratio.

5/1 = (18 - x)/x

5x = 18 - x

6x = 18

x = 3

Marco wrote the equation below.

vova2212 [387]

Answer:

It is true, because the cosine function has a period of 2π

Step-by-step explanation:

Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:

$Cos(\theta)=Cos(2\pi +\theta)$

Taking $\theta$ as $-\frac{\pi}{2}$ , $(2\pi + \theta)$ is equal to $2\pi + (-\frac{\pi}{2})\\=2\pi - \frac{\pi}{2}\\=\frac{4\pi-\pi}{2}\\=\frac{3\pi}{2}$

The equation is true!

<u>Note:</u> The cos function is even function

Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
