Explicação passo a passo:

$\mathsf{3)\:90\textdegree - x = 18\textdegree \iff x = 90\textdegree - 18\textdegree \iff x = 72\textdegree}$

$\mathsf{4)\:90\textdegree - 4x = x \iff 5x = 90\textdegree \iff x = 18\textdegree}$

$\mathsf{5)\:x = 90\textdegree - 2(10\textdegree) \iff x = 90\textdegree - 20\textdegree \iff x = 70\textdegree}$

$\mathsf{6)\:90\textdegree - x = 40\textdegree \iff x = 90\textdegree - 40\textdegree \iff x = 50\textdegree}$
