Question

1. $\triangle abc \cong \triangle gfo$. find $m\angle o$.

Explanation:

Step1: Identify corresponding angles

Corresponding angles: $\angle A = \angle G$, $\angle B = \angle F$, $\angle C = \angle O$
$\angle B = \angle F = 108^\circ$, $\angle A = 31^\circ$

Step2: Calculate $\angle C$ (equal to $\angle O$)

Sum of triangle angles: $180^\circ$
$\angle C = 180^\circ - \angle A - \angle B = 180^\circ - 31^\circ - 108^\circ = 41^\circ$

Answer:

41°
