Answer:

Step-by-step explanation:
<u>Newton's law of cooling states </u>
"<em>that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"</em>
Newton's Law of Cooling is given by the formula

Where
F(
t
) is the temperature of the object at a given time t
T
s
is the surrounding temperature
T
0 is the initial temperature of the object
k is the constant
Given k=0.2
Hence the expression is

The angle stays the same so D = 80 degrees
