To convert a temperature from degrees Celsius to degrees Fahrenheit, we use the following formula:
[tex]\[ F = (C \times \frac{9}{5}) + 32 \][/tex]
Given the temperature [tex]\( C = 20^{\circ} C \)[/tex], let's apply the formula step-by-step:
1. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex]:
[tex]\[ 20 \times \frac{9}{5} = \frac{180}{5} = 36 \][/tex]
2. Add 32 to the result:
[tex]\[ 36 + 32 = 68 \][/tex]
Therefore, [tex]\( 20^{\circ} C \)[/tex] is equal to [tex]\( 68^{\circ} F \)[/tex].
From the given choices:
- [tex]\(20^{\circ} F\)[/tex]
- [tex]\(68^{\circ} F\)[/tex]
- [tex]\(36^{\circ} F\)[/tex]
- [tex]\(32^{\circ} F\)[/tex]
The correct answer is [tex]\(68^{\circ} F\)[/tex].
