The midpoint of line AB is M(6,1).if the coordinates of A are (4,8), what are the coordinates of B?

Midpoint formula :

Here the midpoint of A and B is and the given point is . We need to find the coordinates of B . So , let the point be

Compare ,

And ,

Hence the required coordinate is .

(2, -7)

Step-by-step explanation:

Given:

Now let's assume point B is (x,y), where the x is the coordinate of x and y coordinate of y

The x and y coordinate of a line segment is obtained by adding x and y coordinates, respectively, and then adding by 2

The coordinates of B are (2,-7)

29 is the correct answer

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
