Step-by-step explanation:
Answer:
10+8+6=24 the ratio of taking the biographies to the science books are: 4:3
Step-by-step explanation:
That is the answer because 10+8+6= total 24 books
ratio of biographies= 24:8=3:1
ratio of science fiction= 24:6= 4:1
hence according axiom 1 ab × Ac= aa × BC
3:1×4:1= 4:3

From the figure, we immediately have
cos(θ) = 8/17
sin(θ) = 15/17
By definition of tangent,
tan(2θ) = sin(2θ)/cos(2θ)
Recall the double angle identities:
sin(2θ) = 2 sin(θ) cos(θ)
cos(2θ) = cos²(θ) - sin²(θ) = 2 cos²(θ) - 1
Then
tan(2θ) = (2 sin(θ) cos(θ)) / (2 cos²(θ) - 1)
tan(2θ) = (2 × 15/17 × 8/17) / (2 × (8/17)² - 1)
tan(2θ) = -240/161
