Apot of water on the stove has a temperature increase of 45 c. how much is that temperature increase in degrees fahrenheit?
1. 25 degrees f increase2. 113 degrees f increase3. 57 degrees f increase4. 77 degrees f increase5. 81 degrees f increase

2. 113 degrees F increase

Explanation:

Formula for converting °C to °F is

(°C × 9/5)+32

Where °C is the temperature value in degree Celsius. Given temperature to be 45°C, converting to °F we have;

(45°C × 9/5) + 32

= 81+32

= 113°F

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
