First we should write the total numbers:
12+8+6+4=30
then we should divide the number 30 by 360(because the pie chart is 360 degrees):
$360 \div 30 = 12$

now we should multiply 12(the number of students who likes rock) by 12
$12 \times 12 = 144$
the answer is 144 degrees

<h3>Here is your Answer </h3>

$\frac{1}{2} \times - 2 + \frac{1}{3} \times - 5 \\ \\ = \frac{1}{ \cancel2} \times \cancel{- 2} + \frac{1}{3} \times - 5 \\ \\ = 1 \times - 1 + \frac{1}{3} \times - 5 \\ \\ = - 1 + ( - \frac{5}{3} ) \\ \\ = - 1 - \frac{5}{3} \\ \\ = \frac{ - 3 - 5}{3} \\ \\ = \frac{ - 8}{3} = - 2 \frac{2}{3}$
