Geometry ahh I wish I could help. :'(
Sin (2 pi/3) = sqrt(3)/2
you can get this from the unit circle
9514 1404 393
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°.
The answer is "The empty square has a side length of 10 and an area of 100 square units"
If f(-3)=-9, g(5)=12 and f(5)=1
then g(-7)=-6
