Answer:
(#14 - supplementary) x = 10.5
(#15 - supplementary) x = 10

Explanation:
For these problems, we must know that a supplementary angle can be viewed as a sum of angles that add to 180 degrees. With this known, we can write our equations to find x.

(#14)
15x - 12 + 5x - 18 = 180
20x - 30 = 180
20x = 210
x = 10.5

(#15)
6x + 13 + 14x - 33 = 180
20x - 20 = 180
20x = 200
x = 10

Hope this helps.

Cheers.

Answer:

There are 104.5 centiliters of paint in the mixture.

Step-by-step explanation:

Since you have a total of .50 liters of paint you would just look at the measurement and split it in half which would give you 100 centiliters and then you would add the 4.5 centiliters to the 100 and you would get 104.5 centiliters of paint.

Find all solutions to 2sin(θ)=√3 on the interval 0≤θ<2π
makkiz [27]

Answer:

2sin(3θ) - √3 = 0

Step-by-step explanation:

 sin(3θ) = √3/2

 

3θ = π/3 + 2kπ or 2π/3 + 2kπ, k = 0, ±1, ±2, ±3,...

 

θ = π/9 + 2kπ/3, 2π/9 + 2kπ/3

 

If k = 0, we get θ = π/9, 2π/9

If k = 1, we get θ = 7π/9, 8π/9

If k = 2, we get θ = 13π/9, 14π/9

 

Other values of k give values of θ lying outside of the interval [0, 2π).
