SOLUTION:
Case: Trigonometry
Method:
Let the distance between the Sun and the Earth be 'z'
The relationship between x, y and z is:
[tex]\begin{gathered} tan(x)=\frac{opp}{adj} \\ tan(x)=\frac{y}{z} \\ z=\frac{y}{tan(x)} \\ z=ycot(x) \end{gathered}[/tex]
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.
