Exterior Angles in Triangles and Transversals

Using what you know about triangles and transversals.....What are the correct angle measures for a, b, and c?

• a = 118^o

  b = 30^o

  c = 32^o

• a = 118^o

  b = 32^o

  c = 30^o

• a = 148^o

  b = 16^o

  c = 16^o

• a = 62^o

  b = 58^o

  c = 60^o

What is the value of "y" and the angles?

• y = 27

  angle = 134

• y = 134

  angle = 27

• y = 18.2

  angle = 107.6

• y = 17.8

  angle = 106.4
