First add up all the values. What do you get?

anonymous · Answer

125

jim_thompson5910 · Answer

Good, now divide the amount in the comedy section by this total

jim_thompson5910 · Answer

You're not done yet, but you're close

jim_thompson5910 · Answer

What did you get when you divided

anonymous · Answer

Yeah I know lol, just realized that

anonymous · Answer

5

jim_thompson5910 · Answer

Divide the other way around

jim_thompson5910 · Answer

25/125 = ??

anonymous · Answer

Oops,
0.2 lol

jim_thompson5910 · Answer

So this 0.2 represents the proportion of the number total. Basically, the number of comedies is 20% of the number of movies total.

jim_thompson5910 · Answer

So we just need to take 20% of 360 to get the final answer

anonymous · Answer

Oh alright, so how exactly would I do that? Percentages&decimals&fractions are not my strength lol

anonymous · Answer

$$\frac{25}{25+20+15+22+27+16}*360{}^{\circ}=72{}^{\circ} $$

jim_thompson5910 · Answer

20% of 360 is the same as 0.2 times 360


0.2*360 = 72


So the angle is 72 degrees
