Answer:
42.8°C
Step-by-step explanation:
To convert from degrees centigrade to degrees fahrenheit, we use this formula;
(C × [tex]\frac{9}{5}[/tex]) + 32
Where C is the temperature in degrees centigrade.
So,
(C × [tex]\frac{9}{5}[/tex]) + 32 = 109°F
[tex]\frac{9}{5}[/tex]C = 109 - 32
[tex]\frac{9}{5}[/tex]C = 77
C = 77 × [tex]\frac{5}{9}[/tex] = 42.77777778°C
It equals 42.8°C (rounded up to nearest tenth of a degree centigrade)
