To find the angle \( \angle BOC \) in triangle \( ABC \) where \( \angle A = 60^\circ \) and \( \angle B = 80^\circ \), we can follow these steps: ### Step 1: Find Angle C First, we need to find the measure of angle \( C \) using the triangle sum property. The sum of the angles in a triangle is \( 180^\circ \). \[ \angle A + \angle B + \angle C = 180^\circ \] ...
