e. Find the coordinates of midpoint of the segment joining the points (22. 20)and (0, 16). |
|
Answer» Two points are, (22,20)&(0,16) Lets suppose that the coordinates of midpoint of the segment joining (22,20) and (0,16) is, (x,y) We know that,If coordinates of two points are (x1,y1) and (x2,y2), then the coordinates of midpoint (x,y) joinng the segment of those points are -(x,y) = {(x1+x2)/2 , (y1+y2)/2} lets go back to the question (x,y) = {(x1+x2)/2 , (y1+y2)/2} => x = (x1+x2)/2=> x = (22+0)/2=> x = 11 & => y = (y1+y2)/2=> y = (20+16)/2=> y = 18 So the coordinates of midpoint of segnent joining (22,20) and (0,16) are Like my answer if you find it useful! |
