Answer:
x = 6
= 8.485
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is
times the length of a leg.
So, if you are given the hypotenuse, then divide its length by 
x = 12/
= 12
/2 = 6
= 8.485
(2,3) the order is rise over run so, go up two, and to the right 3 which gives you point D
I don't know the answer because of how zoomed in it is. But, you could make a cordinate grid and plot all of the numbers. Then, you would connect all of the lines and you will see that one line is missing in the parallelogram. You finish off that line yourself and write down the cordanite that you needed to complete the parallelogram. You will lastly put U=answer (the cordanite you got from finishing off the parallelogram).
the solution is where the line cross on the y axis, which is on 0
so y = 0
