Answer:
<R = 26degrees
Step-by-step explanation:
Making <R as the reference angle
Adjacent side = 12.7
Hypotenuse = 14.1
Cos <R = adj/hyp
Cos <R = 12.7/14.1
Cos <R = 0.9007
<R = arccos(0.9007)
<R =25.7
<R = 26degrees

No, as tangents connected to a circle on opposite sides of the diameter would be essentially rays, or continuous lines in one direction, that extend infinitely in opposite directions.

Answer:
1920 k calories is the basal metabolism.
Step-by-step explanation:
Formula to get the total basal metabolism has been given by the formula
R(t) = ![80-0.18cos\frac{\pi t}{12}](https://tex.z-dn.net/?f=80-0.18cos%5Cfrac%7B%5Cpi%20t%7D%7B12%7D)
Where t = time
Now to calculate the total basal metabolism we will integrate the function with respect to time from 0 to 24 hours.
![\int_{0}^{24}R(t)=\int_{0}^{24}(80-0.18cos\frac{\pi t}{12})dt](https://tex.z-dn.net/?f=%5Cint_%7B0%7D%5E%7B24%7DR%28t%29%3D%5Cint_%7B0%7D%5E%7B24%7D%2880-0.18cos%5Cfrac%7B%5Cpi%20t%7D%7B12%7D%29dt)
= ![[80t-{0.18}\times \frac{sin\frac{\pi t}{12}}{\frac{\pi}{12}}]_{0}^{24}](https://tex.z-dn.net/?f=%5B80t-%7B0.18%7D%5Ctimes%20%5Cfrac%7Bsin%5Cfrac%7B%5Cpi%20t%7D%7B12%7D%7D%7B%5Cfrac%7B%5Cpi%7D%7B12%7D%7D%5D_%7B0%7D%5E%7B24%7D)
= ![[(80-0)24-\frac{0.18\times 12}{\pi}(sin2\pi - sin0)]](https://tex.z-dn.net/?f=%5B%2880-0%2924-%5Cfrac%7B0.18%5Ctimes%2012%7D%7B%5Cpi%7D%28sin2%5Cpi%20-%20sin0%29%5D)
= [(80-0)24-(sin2\pi - sin0)]
= 80×24
= 1920 k calories
Therefore, 1920 k calories is the total basal metabolism of the young man.
