Linear pair angles have too add to 180, so

5x+9+3x+11=180
8x+20=180
8x=160
x=20

so angle S is 5*20+9 = 109
angle T is 3*20+11 = 71

N76 [4]

Answer:

<em>There are 1700 books in the library.</em>

Step-by-step explanation:

<em>If 28% of the books is non-fiction, that means the remaining 72% of books are fiction.</em>

If 72% of the books are fiction, 1224/72 will give us 1%, which is 17.

If 1% is 17 books, then 17*100=100% of books.

There are 1700 books in the library.
