Hello,
Let's calculate ∠O:
∠O=180-2*56=68+
x=90-68=22°
Answer:
53.3324
Step-by-step explanation:
given that a thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F.
By Newton law of cooling we have
T(t) = 
where T (t) is temperature at time t,T =surrounding temperature = 40, T0 =70 = initial temperature
After half minute thermometer reads 60° F. Using this we can find k

So equation is

When t=1,
we get

8(8-6v)= using the distributive property
8*8 = 64
8*6v = 48v
8(8-6v) = 64-48v
