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°.

Answer:
So, we get that is P(A)=0.32.
Step-by-step explanation:
We know that:
We have the formula for probability:
So, we calculate:
We calculate:
So, we get that is P(A)=0.32.
Answer:
Euler's Formula = F+V=E+2
F=9
V=14
So, 9+14=E+2
23=E+2
23-2=E
21=E
Hence, E (edges) = 21
Step-by-step explanation:
Answer:
1499
Step-by-step explanation:
Given that :
New discounted price = 1274
Let original price = p
Reduction in original price = 225
Original price is the sum of the reduction and the new discounted price
The Original price = Reduction in original price + new discounted price
P = 225 + 1274
P = 1499
