Cot(5pi/12) = tan(pi/12)
tan(x/2) = (1 - cos(x)) / sin(x))
tan(pi/12) = tan((pi/6)/2) = (1 - cos(pi/6)) / sin(pi/6))
sin(pi/6) = 1/2
cos(pi/6) = sqrt(3) / 2
so...
tan(pi/12) = (1 - sqrt(3)/2) / (1/2) = 2 - sqrt(3)
Answer:
212 km/h
Step-by-step explanation:
12/2 = 6
A 6% increase for a speed of 200 km/h
= 200 * 106%
= 212 km/h
Hope this helped!
