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°

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

The answer is "a"radius = 12.7 unitsdiameter = radius × 212.7 units × 2 = 25.4 units
