Answer:

x = 1/20 y^2

Step-by-step explanation:

This is a rightward opening  (sideways ) parabola

Directrix = x = -5

Distance formula form point x,y  to directrix and focus are equal:  

(x - -5)^2 = (x-5)^2 + y^2

x^2 + 10x + 25 = x^2 - 10x  + 25 + y^2

20x = y^2

x = 1/20 y^2

We can draw a square with given side many ways. Square means the sides are equal in length. The diagonals are equal and bisect each other in mutually perpendicular.One method is first we draw a line segment equal to AB. The end points are marked as A and B. From these points draw a perpendicular, using scale or compass mark the points on this perpendicular equal to AB. these points be C and D. Join these point C and D get CD. Now the square is ready. ABCD is the square.

The inscribed polygon can be square or a hexagon.

<h3>What is polygon'?</h3>

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end.

First,

if we join A to B, B to C, C to D and D to A then a square will be formed.

But, if we join passing through the arc intersecting point then join to B then again join to a line passing through arc intersecting then to D.

A six side figure will obtain named as hexagon.
