From the figure, we observe that,

All the horizontal lines are parallel to each other.

Hence,


h=g=90^(\circ)

Using the linear pair,


\begin{gathered} i+h=180^(\circ) \\ i+90^(\circ)=180^(\circ) \\ i=90^(\circ) \end{gathered}

Hence, the answers are,


\begin{gathered} i=90^(\circ) \\ g=90^(\circ) \\ h=90^(\circ) \end{gathered}
