Triangle Constructions II

The purpose of today's activity is to construct triangles with certain constraints.
Use the applet below to create triangle ABC with the following constraints. AB=12cm, AC=7cm, and angle ABC=20°
Use the applet below to create triangle ABC with the following constraints. AB=8cm, angle BAC=25°, and angle ABC=120°

In the second Triangle what was the measure of angle ACB?
