Answer:
Step-by-step explanation:
WXYZ is a rhombus with vertices W(0,4b), X(2a,0), Y(0,-4), Z(-2,0). You can see thap points W and Y lie on the y-axis and points X and Z lie on the x-axis. Then the centre of the rhombus is origin, thus W and Y are symmetric about the origin. Then b=1 and point W has coordinates (0,4). Similarly points X and Z are symmetric about the origin and a=1, hence X(2,0).
Let KLMN be middlepoints of segments WX, XY, YZ, ZW, respectively. Then
.
Now find the vectors
,
,
and
:
that means that
.
Similarly,
,
,
.
You prove that KLMN is a recctangle.
Answer: WY = 27
Step-by-step explanation:
Due to WX being a Perpendicular Bisector WY = WZ
4x - 5 = 2x + 11
Add 5 to both sides
4x = 2x + 16
Subtract 2x from both sides
2x = 16
Divide by 2
x = 8
So 4x - 5 of x = 8
4*8 = 32 - 5 =27
