Option C: The distance between the two points is 7.8 units
Explanation:
Given that the two points are (-2,4) and (3,-2)
<u>Distance between the two points:</u>
The distance between the two points can be determined using the formula,
Substituting the coordinates (-2,4) and (3,-2), we get,
Simplifying the terms, we get,
Squaring the terms, we have,
Adding, we get,
Thus, the distance between the two points is 7.8 units
Therefore, Option C is the correct answer.
The internal angle sum of a quadrilateral is :
C. 360°
The sum of internal angles of a polygon is determined by a formula :
where n represents number of sides.
In a quadrilateral there are four sides,
So, plugging 4 in the formula :
