Explicação passo-a-passo:

$\mathsf{x = \dfrac{S - (2 \times 75\textdegree)}{3}}$

$\mathsf{x = \dfrac{[(n - 2) \times 180\textdegree] - (2 \times 75\textdegree)}{3}}$

$\mathsf{x = \dfrac{[(5 - 2) \times 180\textdegree] - (2 \times 75\textdegree)}{3}}$

$\mathsf{x = \dfrac{[3 \times 180\textdegree] - (2 \times 75\textdegree)}{3}}$

$\mathsf{x = \dfrac{540\textdegree - 150\textdegree}{3}}$

$\mathsf{x = \dfrac{390\textdegree}{3}}$

$\boxed{\boxed{\mathsf{x = 130\textdegree}}}$
