Answer:

$(10, 0)$

Step-by-step explanation:

Let's try all the options:

$\left \{ {{2x + y = 20} \atop {4x-2y = 40} \right.$

Considering $(10, 0)$ :

$$\left \{ {{2(10) + 0 = 20} \atop {4(10)-2(0) = 40} \right. $\\$

$\left \{ {{20 + 0 = 20} \atop {40-0 = 40} \right.$

$\left \{ {{20= 20} \atop {40 = 40} \right.$

Considering $(0, 10)$ :

$$\left \{ {{2(0) + 10 = 20} \atop {4(0)-2(10) = 40} \right. $\\$

$\left \{ {{0 + 10 = 20} \atop {0-20 = 40} \right.$

$\left \{ {{10= 20} \atop {-20 = 40} \right.$

$\left \{ {{10\neq 20} \atop {-20 \neq 40} \right.$

Considering $(4, 2)$ :

$$\left \{ {{2(4) + 2 = 20} \atop {4(4)-2(2) = 40} \right. $\\$

$\left \{ {{8 + 2 = 20} \atop {8-4 = 40} \right.$

$\left \{ {{10= 20} \atop {4 = 40} \right.$

$\left \{ {{10\neq 20} \atop {4 \neq 40} \right.$

Considering $(10, -10)$ :

$$\left \{ {{2(10) -10 = 20} \atop {4(10)-2(-10) = 40} \right. $\\$

$\left \{ {{20 -10 = 20} \atop {40+20 = 40} \right.$

$\left \{ {{10= 20} \atop {60 = 40} \right.$

$\left \{ {{10\neq 20} \atop {60 \neq 40} \right.$

igor_vitrenko [27]

SOLUTION:

Case: Trigonometry

Method:

Let the distance between the Sun and the Earth be 'z'

The relationship between x, y and z is:

$\begin{gathered} tan(x)=\frac{opp}{adj} \\ tan(x)=\frac{y}{z} \\ z=\frac{y}{tan(x)} \\ z=ycot(x) \end{gathered}$

Final answer:

In sentence,

The distance between the Sun and the Earth is the product of the distance between the Earth and the moon and the cotangent of the angle x formed using the lines from the Earth and the moon.
