Step-by-step explanation:
To find Tan of something, the equation if TOA
T = tan
O = opposite
A = adjacent
so
TOA = tan C =
tan c = or 24/7
Step-by-step explanation:
so we can safely say that one train will be there for 3.5 minutes and it will be gone for 16 minutes before another train comes and repeats the cycle.
we want how many minutes that the train will not be there over the total time that is possible so that would be
16/(16+3.5)
16/19.5
32/39
Hope that helps :)
