Anybody know this? I’m not sure how to do it at all.

Answer:
1. 70°
2. 42°
Step-by-step explanation:
they are both isosceles Triangles as both diagrams state that they have two sides the same length. therefore their base angles will be equal.
1. 55 + 55 = 110
180 - 110 = 70°
2. 180 - 96 = 84
84/2 = 42°
