Question

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

Answer 1

1. 70°

2. 42°

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°

Answer 2

2 is 42 but i’m not sure about one
