Step-by-step explanation:

We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that

$(x^2 + \dfrac{1}{x})^3=(x^2)^3+3(x^2)^2\dfrac{1}{x}+3x^2(\dfrac{1}{x})^2+(\dfrac{1}{x})^3\\\\=x^6+3x^4\dfrac{1}{x}+3x^2\dfrac{1}{x^2}+\dfrac{1}{x^3}\\\\=x^6+3x^3+3+\dfrac{1}{x^3}$

Step-by-step explanation:

So the total angle amount of a square is 360

angle B and angle D is equal, forming a equation.

6x-96=3x

simplify that...

x=32

Now pluggin x into the equation (6x-96)&(3x)

96 and 96

Now add all the angles forming this equation: (?+102+96+96=360)

?=66
