Question

Which sets of values can be the measures of the exterior angles of a triangle? 120°, 110°, 130° 35°, 103°, 122° 123°, 87°, 220° 120°, 120°, 120° 123°, 157°, 90°

Answer 1

Answer:

The values are :

• we khow that the sum of a triangle angles is 180°
• the sum of each set  exterior and interior angle is 360°
• so 360+360+360-180 = 900 is the sum of exterior angles of a triangle
• we can see no set can satisfy this condition
