Best guess is it’s the second one but I believe it’s between A and B sorry If I’m wrong.
Step-by-step explanation:
Convert metre to centimetre
Recall: 1m = 100cm
That means,
3m = 3 * 100cm = 300cm
Now we compare them since they have the same unit.
300cm : 6cm
50 : 1
Answer = 50 : 1
no, it's not a square root that we need to identify
Since the equations are not shown, I believe that it could possibly be cos T = 4/17
