Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons
so this is the formula
c² - b² = x²
insert the numbers on the triangle in the picture
21² - 8² = 377
since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~
Answer: x = 19.4
True the circle is a congruent to the radius of an inscribed regular polygon inside the circle
P is less than 200
im pretty sure thats it

1. The remaing area of the yard will be found as follows:
Area of the yard
A1=length*width=10x*15x=150x^2 yd^2
area of the fountain
A2=πr²
A2=π(4x)²
=50.266x^2
The remaining area will be:
A=150x^2-50.266x^2
A=99.735x^2 yd^2
2] Area left for bleachers, restrooms and other parts of the stadium will be as follows:
Area of the lot is:
A1=length*width
A1=8x×12x= 96x^2
Area of the field
A2=length×width
A2=3x×6x=18x^2
Hence the remaining area will be:
A1-A2
=96x^2-18x^2
=78x^2 sq. units
