Answer:
2sin(3θ) - √3 = 0
Step-by-step explanation:
sin(3θ) = √3/2
3θ = π/3 + 2kπ or 2π/3 + 2kπ, k = 0, ±1, ±2, ±3,...
θ = π/9 + 2kπ/3, 2π/9 + 2kπ/3
If k = 0, we get θ = π/9, 2π/9
If k = 1, we get θ = 7π/9, 8π/9
If k = 2, we get θ = 13π/9, 14π/9
Other values of k give values of θ lying outside of the interval [0, 2π).
Answer:
745.5 ft
Step-by-step explanation:
Reference angle (θ) = angle of depression = angle of elevation = 28° (alternate angles are congruent)
Opposite side = 350 ft
Hypotenuse = x
Apply the trigonometric function, SOH:
Sin θ = Opp/Hyp
Sin 28° = 350/x
x = 350/Sin 28
x = 745.5 ft (nearest tenth)
your answer is 39.3700787 inches
Answer:
-21
Step-by-step explanation:
Each of those lines is -3
If you look at the -10, it goes down 2 lines and goes to -16 meaning that if it only went down one line it would only go to -13
Showing that each line is worth -3
It goes down 2 lines from -16 (-6)
so if you go down 6 from -16 that would get you to -21
