Answer:
Use 1.75 cups of blue and 1 cup of yellow
Step-by-step explanation:
The given problem can be placed in the category of ratios and proportions. There is a ratio of color mixing which contains the proportion of two colors i.e blue and yellow. When we use 2 cups of yellow with 3.5 cups of yellow then we get green color so if we mix half of their amounts then we can get less or simply half amount of color too. Hence adding 1 cup of yellow and 1.75 cup of blue will give us small amount in result.
I hope this helps have a great day :)

60° is 4x 15° because:
![60 \div 15 = 4 \\ 15 \times 4 = 60](https://tex.z-dn.net/?f=%2060%20%5Cdiv%2015%20%3D%204%20%5C%5C%2015%20%5Ctimes%204%20%3D%2060%20)
I would first divide by 2:
![60 \div 2 = 30](https://tex.z-dn.net/?f=%2060%20%5Cdiv%202%20%3D%2030%20%20)
Then divide by 2 again:
![30 \div 2 = 15](https://tex.z-dn.net/?f=%2030%20%5Cdiv%202%20%3D%2015%20)
That leaves you with a 15° angle.
