Answer:
D
Step-by-step explanation:
There are 1.61 km in 1 mi.
10 mi × (1.61 km/mi) = 16.1 km
I don't think that's possible.
Sin A = opp/hyp = 4/5
Cos A = adj/hyp = 3/5
Tan A = opp/adj = 4/3
Cos 27 = 0.8910065... --> 0.89
You can just plug that into your graphing calculator, just make sure the degree mode is on.
