Answer:
he used 5 1/3 everything else is to low or high
The overall temperature would be 3.6°F as this is how much it was changed by
Answer=3.6°F
I = 8.
k = 4
j = sqrt(8^2 + 4^2) = 8.944.
Assumed
PW as 100
FW as twice PW as 200
answer is 7.27254 years
manually take the log of both sides and solve for n
angles in a triangle add up to 180
so x = 180 - ( 70 + 90 ) = 20
this is because the two other angles in the both of the identical triangles are 70 and 90
