Answer:
6*
Step-by-step explanation:
The time difference is 4 hours, (since 8am +4 = 12pm), and the temperature change is 6* because -2*+6*=4*.
Answer:

Step-by-step explanation:
As given in figure 1 below:
FK = a, m∠F = 45° and m∠L = 30°
Construction: Draw an altitude KE from point K on FL.
Now, In ΔFEK,
FE = EK (Sides opposite to equal angles of a triangle)
Let FE = EK = x
Now, using pythagoras In ΔFEK,



∴ FE = EK = 
Now in ΔEKL, EK = 
Using trigonometry ratio,
TanФ = Altitude\ Base

Tan 30° = 


Now FL = FE + EL
FE =
and 
∴
