Answer:
A
Step-by-step explanation:
The interior angle measurements of a triangle must all add up to 180 degrees, so to find out which of these would work, we just have to add them.
A: 22, 61, 97
22 + 61 + 97 = 180
These angles add up to 180 degrees, so they work!
B: 45, 45, 60
45 + 45 + 60 = 150
These angles do not add up to 180 degrees, so they don't work.
C: 39, 42, 37
39 + 42 + 37 = 118
These angles do not add up to 180 degrees, so they don't work.
D: 60, 110, 30
60 + 110 + 30 = 200
These angles do not add up to 180 degrees, so they don't work.
