Explicação passo a passo:

$\mathsf{x + 75\textdegree = 180\textdegree}$

$\mathsf{x = 180\textdegree - 75\textdegree}$

$\boxed{\boxed{\mathsf{x = 105\textdegree}}}$

$\mathsf{y + 120\textdegree = 180\textdegree}$

$\mathsf{y = 180\textdegree - 120\textdegree}$

$\boxed{\boxed{\mathsf{y = 60\textdegree}}}$

$\mathsf{x + y + z = 180\textdegree}$

$\mathsf{105\textdegree + 60\textdegree + z = 180\textdegree}$

$\mathsf{z = 180\textdegree - 165\textdegree}$

$\boxed{\boxed{\mathsf{z = 15\textdegree}}}$
