Answer:
Step-by-step explanation:
Do you have a picture of the problem?
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)
Oy= - 3x please give me beainliest answer
Explaination: when there is two negatives it would turn into a positive bit there are positives too so it would stay negative and yeah
The perimeter is 50 units
