Answer:
4 1/8km
Step-by-step explanation:
if you have done 3 1/4km you can multiply the fraction by 2 so you get 3 2/8.
so now we have 2 5/8km and 3 2/8.
(its always easier to have the fractions the same denominator)
now we add the whole numbers first.
2 km + 3km = 5km.
now the fractions.
5/8 km + 2/8 km = 7/8km.
now add them both together and we get.
5 7/8 km.
take that answer away from 10.
we get 4 1/8km.

Answer:
48°
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(α) = (350 m)/(470 m) = 35/47
α = arcsin(35/47) ≈ 48.13°
The angle of elevation of the plane is about 48°.
