Answer:
Rig
Step-by-step explanation:
Pi/6 = 180°/6 = 30°
This produces a triangle that has 30-60-90 angles.
Its short leg will measure = y = sinΘ
Its long leg will measure = x = √1-y² = sin(2Θ)
Its hypotenuse will measure = 1
Tangent Θ = opposite / adjacent or short leg / long leg
Tan(pi/6) = 1/3 √3
Answer:

-3/-1
Step-by-step explanation:
L=k/r^2,
r^2 is the denominator cause L varies inversely with the square of distance
The answer is B
Yes the line of the first angle measured 50 is 60
