Answer:
41.4 degrees
Step-by-step explanation:
Find cos x by dividing both sides of this equation by 4:
cos x = 3/4 = 0.75
Using a calculator's inverse cosine function, find x:
arccos 0.75 = 0.723 radian, or
0.723 rad 180 deg
--------------- * ------------- = 41.4 degrees
1 pi rad
Answer:
Hi,Do you still have geometry ??
Step-by-step explanation:
You can't do 140 divided by 18
or it will end up like this <span>7.77777777778</span>
Answer:
148 degrees
Step-by-step explanation:
The angles are supplementary so if you subtract 32 from 180, you get <em><u>148 degrees. </u></em>
Answer:
K-a Positive constant that depends on the area and nature of the surface of the body under consideration.
Step-by-step explanation:
Newtons law cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small. The formula is given as:
where,T- temperature at time t,
is temperature of the surrounding and k- A Positive constant that depends on the area and nature of the surface of the body under consideration.
