Question

for each pair of angle measures, decide if the angles are complementary, supplementary, or neither. complementary 12° and 78° supplementary 80° and 100° neither 50° and 50° 25° and 155°

Explanation:

Step1: Check complementary (sum=90°)

$25^\circ + 155^\circ = 180^\circ
eq 90^\circ$

Step2: Check supplementary (sum=180°)

$25^\circ + 155^\circ = 180^\circ$

Step3: Determine category

Sum equals 180°, so supplementary.

Answer:

Supplementary (the middle box labeled "Supplementary" with 80° and 100°)
