we are given
exterior angle is 18
so,
now, we can use formula
number of sides of regular polygon = 360/(exterior angle)
so, we get
so, number sides is 20..........Answer
PLEASE HELP ASAP. SOLVE FOR X AND Y. SHOW ALL WORK.

The solution to the system of equations is (-3.88, 0.66) and (3.04, 1.09)
<h3>How to determine the solution to the system of equations?</h3>The system of equations is given as:
x^2y + yx^2 = 20
1/x + 1/y = 5/4
Multiply through the equation 1/x + 1/y = 5/4 by 4xy
So, we have:
4x + 4y = 5xy
So, we have the following system of equations
4x + 4y = 5xy
x^2y + yx^2 = 20
Next, we plot the graph of the system of equations
4x + 4y = 5xy
x^2y + yx^2 = 20
See attachment for the graph of the system
From the attached system, we have the point of intersection to be
(x, y) = (-3.88, 0.66) and (3.04, 1.09)
Hence, the solution to the system of equations is (-3.88, 0.66) and (3.04, 1.09)
