Respuesta :

Answer:

120°, 110°, 130°

120°, 120°, 120°

Step-by-step explanation:

The sum of the exterior angles of a triangle = 360

120 + 110 + 130 = 360  OK

35 + 103 + 122 = 260  these cannot be the exterior angles of the triangle

123 + 87 + 220 = 430  these cannot be the exterior angles of the triangle

120 + 120 + 120 = 360   OK

123 + 157 + 90 = 370   these cannot be the exterior angles of the triangle
