Answer 1

A landslide is defined as themovement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.

HERE IS UR ANSWER

$_____________________________$

We know that the distance between the two points (x1,y1) and (x2,y2) is 

$d= \sqrt{} (x2−x1) {}^{2} +(y2−y1) {}^{2}$

Let the given vertices be A=(−2,1), B=(4,6) and C=(6,−3)

We first find the distance between A=(−2,1) and B=(4,6) as follows:

AB=

$\sqrt{} (x2−x1) {}^{2} +(y2−y1)2 {}^{2} \\ = \sqrt{} (4−(−2)) {}^{2} +(6−1) {}^{2} </p><p>     = \sqrt{} (4+2) {}^{2} +52 {}^{2} = \sqrt{?} {6}^{2} + {5}^{2} = \sqrt{} 36+25 = \sqrt{61} </p><p>$
