...
Identify the ones that are supplementary:
175° and 5° 5 °
137° and 93° 93 °
60° and 60° and 60° 60 °
26° and 116° 116 °
90° and 90° 90 °
85° and 95° 95 °
150° and 31° ...
100° and 80°
Answer:
B & C
Step-by-step explanation:
Supplementary means it equals to the sum of 180.
a) 30 + 60 + 60 = 150
It is less than 180.
b) 45 + 45 + 90 = 180.
This is a possible answer.
c) 72 + 28 + 80 = 180
This is a possible answer.
d) 25 + 75 + 100 = 200
This is greater than 180.
e) 180 + 180 + 180 = 540
This is greater than 180.
