$\sqrt{( \sqrt{7-2 \sqrt{10} }+ \sqrt{2} )*2 \sqrt{5} }= \\ = \sqrt{( \sqrt{2-2 \sqrt{2*5}+5 }+ \sqrt{2} )*2 \sqrt{5} }= \\ \sqrt{( \sqrt{( \sqrt{2}- \sqrt{5})^{2} }+ \sqrt{2} )*2 \sqrt{5} }= \\ \sqrt{( \sqrt{5}- \sqrt{2} + \sqrt{2} )*2 \sqrt{5} }= \\ \sqrt{ \sqrt{5} *2 \sqrt{5} }= \\ \sqrt{2*5} = \sqrt{10}$

A marine biologist needs to put a GPS device underwater, halfway between two tracking stations to help document great white shar

The location of the GPS device will be ( 75,-45).

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The given coordinates of the stations are ( -50,-25) and (200,-65).

The midpoints for the two coordinates will be calculated by the formula given below:-

$\rm Mid points= (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$
