Of the trains that recently arrived at Bluepoint Station, 10 were on time and 5 were late. Considering this data, how many of the next 9 trains would you expect to be on time? All I'm getting it 4.5

345

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
