Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13
Answer:

Step-by-step explanation:
The vertical angles have the same measure, so ...
3x +50 = 6x -10
60 = 3x . . . . . add 10-3x
20 = x . . . . . . divide by 3
Answer:
length equals to 22 bcoz the width is 13*2=26 and than u do 70 minus 26 to get 44 than divide by 2 to get the length 22
