Answer:
The formula to calculate the Celsius temperature for a given Fahrenheit temperature is:
Step-by-step explanation:
Given formula:
where 
represents temperature in Fahrenheit and 
represents temperature in Celsius.
To solve the equation for .
Solution:
We have,
Subtracting both sides by 32.
Dividing both side by 1.8
∴
Using the above formula, we can calculate the Celsius temperature for a given Fahrenheit temperature.
C+a=166
a=166-c
5.3c+9.2a=1254.2
5.3c+9.2(166-c)=1254.2
5.3c+1527.2-9.2c=1254.2
5.3c-9.2c=1254.2-1527.2
-3.9c=-273
c=-273/-3.9
c=70

Step-by-step explanation:
Answer:
x = 85 deg
Step-by-step explanation:
We can see that there are two straight lines that intersect and that the two angles given are opposite angles.
Because they are opposite angles, the two angles have the same value, i.e
(x + 5) = 90 (subtract 5 from each side)
x = 90 - 5
x = 85 deg
