Which equation can be used to solve for x in the parallelogram below?

densk [106]

Answer:

B. (3x - 12)° = (2x + 8)°

Step-by-step explanation:

This equation can be used to solve x.

3x - 12 = 2x + 8

3x - 2x = 12 + 8

x = 20°

-------------------------------------------------------------------

Verification:

3(20) - 12 = 2(20) + 8

60 - 12 = 40 + 8

48° = 48°

A sine function increasing through the origin can be used to model light waves. Violet light has a wavelength of 400 nanometers.

andrew11 [14]

Answer:

(2) (100, 300)

Step-by-step explanation:

One wave can be divided on 4 parts, as show on the picture.

Since a length of one whole wave equals 400, a length of each part is $400:4=100$ nanometers.

The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).

Santos walks 2 kilometers south and then a certain number of kilometers east. He ends 5 kilometers away from his starting positi

IgorLugansk [536]

Answer:

$\sqrt{21}\ km$ or $4.58\ km$

Step-by-step explanation:

we know that

Applying Pythagoras' Theorem, calculate how many kilometers eastward Santos walked

Let

x----> quantity of kilometers eastward that Santos walked

$x^{2}=5^{2}-2^{2}$

$x^{2}=21$

$x=\sqrt{21}\ km$ ----> exact value

$\sqrt{21}=4.58\ km$ -----> approximate value
