Angle 10 is 140 degrees

Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)

Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50

How do you solve for the quotient of (x^-1) - 1 ÷ x - 1?

Ber [7]

$\bf x^{-1}-1\div x-1\implies \implies \cfrac{1}{x}-1\div x-1\implies \cfrac{\frac{1}{x}-1}{~~x-1~~}\implies \cfrac{~~\frac{1-x}{x}~~}{\frac{x-1}{1}} \\\\\\ \cfrac{1-x}{x}\cdot \cfrac{1}{x-1}\implies \cfrac{-(\begin{matrix} x-1 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix})}{x}\cdot \cfrac{1}{\begin{matrix} x-1 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}}\implies -\cfrac{1}{x}\implies -x^{-1}$
