Hope this attached file will help u.
To know if Diagonals are perpendicular we need to know two line's slope
If two lines are pependicular their slope m1×m2=-1
For if they are making rhombus two opposite equal sides so u need to know the distancebetween the points.

Answer:
y = 8
Step-by-step explanation:
You will get the same value for y whether you approach the problem by making corresponding angles equal, or by making corresponding sides equal. The equation for the sides takes less work to solve.
2y -3 = y +5
y = 8 . . . . . . . . add 3-y to both sides
_____
<em>Check</em>
This value of y makes the angles ...
(6y -5)° = (6·8 -5)° = 43°
(4y +11)° = (4·8 +11)° = 43°
Corresponding angles and the side between them have the same measures, so the triangles are congruent by ASA.
Answer:
well,the solution is x=4 y=0.... if that helps
