Answer:
Arc length is 
, or, 14.7
Step-by-step explanation:
AB is an arc intercepted by 140 degree angle. The formula for length of an arc is given by
Where
AL is the arc length
is the angle (in our case, 140)
r is the radius of the circle (which is 6)
<em>Substituting, we get:</em>
<em>

<em>In decimal (rounded to tenths) - 14.7</em>
Answer:
99.8, 101.1, 106.3, 110.5

Answer:
Part I: cot(15 degrees) = cot(45 - 30)
Part II: Evaluation is below
Step-by-step explanation:
<em>Everything is done in degrees</em>
<em />
Two angles that differ by 15 degrees that is easy to evaluate is 30 degrees and 45 degrees. The cot(15 degrees) = cot(45 - 30) = 1/tan(45-30) = (1+tan45tan30)/(tan30 - tan45) = (1+ sqrt(3))/(sqrt(3) - 1)
We rationalize this by multiplying 1+ sqrt(3) in the top and bottom, getting:
(4 + 2sqrt(3))/2 = 2 + sqrt(3)
I hope this helps! :)
Your answer would be B. x= -5.
Hope this helps.
