If the point (3,5)is the point of intersection of the diagonals of parallelogram two of whose vertices are at the points (1,2) and (4,3),find the co-ordinate of the remaining corners.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the answer is 8/21

hope this

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
