Answer:
D' (1, 3)
Step-by-step explanation:
When reflected across the y = x line, the "x" and "y" coordinates switch.
If D is (3, 1), then:
x = 3
y = 1
Switch the "x" and "y" values, and rewrite as (x, y).
x = 1
y = 3
D' (1, 3)
The statement that proves that parallelogram KLMN is a rhombus is. The slope of KM is 1 and the slope of NL is –1.
<h3>What is a Rhombus?</h3>
This is a type of quadrilateral that has four sides of which they are all equal.
Hence, given that KLMN is a parallelogram, K(7,7), L(5,3), M(1,1) and N(3,5).
We know that they bisect each other and if the diagonals of a parallelogram are perpendicular to each other then the parallelogram is a rhombus.
Therefore, The slope of KM is 1 and the slope of NL is –1.

Answer:
I belive it would be x<84
Step-by-step explanation:
please let me know if i am wrong
I believe x is 43.
3x+17+x-9=180 It is 180 because a straight line is 180 degrees
4x+8=180
-8 -8 subtraction property of equality
---------------
4/4x=172/4 division property of equality
x=43 solution
