Explicação passo a passo:

$\mathsf{x + 90\textdegree + 2x = 60\textdegree = 360\textdegree}$

$\mathsf{3x + 150\textdegree = 360\textdegree}$

$\mathsf{3x = 210\textdegree}$

$\boxed{\boxed{\mathsf{x = 70\textdegree}}}$

$\mathsf{S_I = (n - 2)\:.\:180\textdegree}$

$\mathsf{105\textdegree + 105\textdegree + x + x + x = (5 - 2)\:.\:180\textdegree}$

$\mathsf{3x + 210\textdegree = (3)\:.\:180\textdegree}$

$\mathsf{3x + 210\textdegree =540\textdegree}$

$\mathsf{3x =330\textdegree}$

$\boxed{\boxed{\mathsf{x = 110\textdegree}}}$
