Answer 2

Answer:

Step-by-step explanation:

There's only 1 angle to find.

45 + 57 + ? = 180                    All triangles have interior angles that add to 180.

102 + ? = 180                          Combined 45 and 57  Subtract 102 from both sides

? = 180 - 102                           Combine

? = 78
