Solução:

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf a = 128^\circ \quad \gets \tex{\ {\^a}ngulo ~ corresponte ~ s{\~a}o ~ iguais} \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf a +b = 180^\circ \quad \gets \tex{\ {\^a}ngulo ~ suplementares ~ somam ~180^\circ} \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf 128^\circ +b = 180^\circ \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf b = 180^\circ -128^\circ \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf & \sf b = 180^\circ -128^\circ \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf & \sf b = 52^\circ \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf c = a \quad \gets \tex{\ {\^a}ngulo ~ oposto ~ pelo ~ v{\'e}rtice \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf c = 128^\circ \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf d = b \quad \gets \tex{\ {\^a}ngulo ~ corresponte ~ s{\~a}o ~ iguais} \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf d = 52^\circ \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf f = 128^\circ \quad \gets \tex{\ {\^a}ngulo ~ oposto ~ pelo ~ v{\'e}rtice \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf g = d \quad \gets \tex{\ {\^a}ngulo ~ oposto ~ pelo ~ v{\'e}rtice \end{array}\right$

$\large \sf \displaystyle \left\begin{array}{l l l l l } \sf g = 52^\circ \end{array}\right$
