Question 194234
A charity obtains its income from various sources -advertising 30000$, donations x, fees 9000$, investments 3000$. sponsorship 10000$. A pie is drawn to illustrate the data.Given that the angle of the sector representing Donations was 204degrees, calculate 
---------------------------------
If donations occupies 204 degrees, then advertising, fees, investments, and sponsorship occupy 156 degrees in a ratio of 9:3:10:3
9n + 3n + 10n +30n = 156
52n = 156
n = 3 degrees
Then 9n = 27 degrees (fees)
3n = 9 degrees (investments)
30n = 90 degrees (advertising)
10n = 30 degrees (sponsorship)
------------
Since x occupies 204 degrees, donations amounts to 204/3 = 68 degrees or 68000$

(A) the total income
(b) the value of x, 
(C) the angle of each of the remaining sectors
