This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!
The equation of the line about which the quadrilateral is reflected will be y = x.
<h3>What is a reflection of the point?</h3>
It is the image of the point which is located in the opposite direction of a given point.
The rule of the refection is given will be
Firstly, the rule for reflecting a point about the line y = x is;
While reflecting on the line y = x, we get the reflected points by swapping the coordinates.
First, draw the line on the graph. Then reflect each vertex of quadrilateral across the line to produce quadrilateral.
Vertex Preimage Coordinates Vertex Image Coordinates
A (-3,-2) A' (-2,-3)
B (-2,-1) B' (-1,-2)
C (-1,-2) C' (-2,-1)
D (-1,-4) D' (-4,-1)
The diagram is given below.
More about the reflection of the point link is given below.

9x^2-42x+49... Sorry if I'm too late!
thats the graph for you answer
