Answer:
10
Step-by-step explanation:
You have to get 10 because g(x) means 5 so you multiply it by two.
Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
Check my math, as I just did it in my head
Based on the scenario, the initial temperature would be :
28 = (60) (1/2)^x/30 + 20
(60) (1/2)^0/30 + 20 = 60 + 20 =
80 C
