6.3 - (4.9 - 7.8)
6.3 - 4.9 + 7.8
1.4 + 7.8
9.2
Answer:
D) 9.2
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
Answer: Dao will pay $ 15,219.2
Step-by-step explanation:
Hi, to answer this question we have to multiply the price of the automobile by the percentage discount in decimal form (divided 100)
18,560 (18/100) = 18,560 (0.18) = $ 3,340.8 (discount amount)
Finally, we have to subtract the discount amount to the automobile's price:
18,560- 3,340.8 =$ 15,219.2
Dao will pay $ 15,219.2.

Answer:
53.13⁰
Step-by-step explanation:
Use sine:
sinθ=opposite/hypotenuse
sin∠A=4/5
∠A=sin⁻¹(0.8)=53.13010235415≈53.13⁰
