Question

20 select all the correct answers. 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°

Explanation:

Step1: Recall exterior - angle sum property

The sum of the exterior angles of any triangle is always 360°.

Step2: Check each set of angles

For the set 120°, 110°, 130°:

$120 + 110+130=360$

For the set 35°, 103°, 122°:

$35 + 103+122 = 260
eq360$

For the set 123°, 87°, 220°:

$123+87 + 220=430
eq360$

For the set 120°, 120°, 120°:

$120+120 + 120=360$

For the set 123°, 157°, 90°:

$123+157+90 = 370
eq360$

Answer:

120°, 110°, 130°; 120°, 120°, 120°
