Answer:
French=60,History=120,Music=108
Explanation:
I think this is trying to represent the degrees of a pie chart.
To find the degree of the pi chart per person you need to 72/12=6
Than to find the amount of degrees per subject multiply 6*amount of students.
Example:
![6 * amoumt \: of \: students \:taking \: music = 6 * 18 = 108](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9fkpa5d85hpsgvlw71ofie2wyh8fazepkb.png)
