3x+17+5=7x+10
3x+22=7x+10
3x-7x=10-22
-4x-=-12
4x=12
X= 12/4
X=3
Am not the best at math but 650.94 would be my answer.
1. Given
2. AD is parallel to BC
3. ∠3 ≅ ∠2
4. transitive property of congruence
5. Definition of bisect
1.
If we are given 2 points A(a, b) and B(c, d),
the midpoint M, of segment AB has coordinates:

2.
We are given the points A(2, 3) and B(10, 3)
the midpoint of AB, is given by the above formula:

3.
Remark, since the segment is horizontal, that is the y-coordinate of both points is 3, the y coordinate of the midpoint will also be 3.
While the x coordinate is still found by

Answer: (6, 3)
