The relation between the Celsius and Fahrenheit scales of temperature is given by: C=5/9 (F-32) Find F if; a) C is 40 b) C is -40​

Option 1 is correct that is square root of 18.

Step-by-step explanation:

We will use pythagoras theroem to find the length of hypotenuse

Here, c is hypotenuse,a is one leg and b is the other leg.

Here, a=b=3

On substituting the values in the formula we get:

Hence, Option 1 is correct that is square root of 18.
