If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°

Tiffany: x/3 books
Brother: (4/9)x - 15 books
Sister: x/3 - x/9
Total: x/3 + (4/9)x - 15 + x/3 - x/9
The LCD here is 9. Mult. all terms by 9 and simplify the resulting expression:
3x + 4x - 135 + 3x - x = 7x + 3x - x - 135 = 9x - 135 books (answer)
