R / (r + g) = 1/5 === 5r = r + g === 4r = g
<span>(r + 5) / (r + 5 + g) = 1/3 --- 3r + 15 = r + 5 + g </span>
<span>2r = g - 10 ... 4r = 2g - 20 </span>
<span>g = 2g - 20 </span>
<span>g = 20 .... 4r = g ... r = 5 </span>
<span>20 green and 5 red </span>

Step-by-step explanation:
Formular for cube volumes:
![{ \tt{volume = (side \times side \times side)}} \\ { \tt{v = (s_{1} \times s_{2} \times s_{3}) }}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7Bvolume%20%3D%20%28side%20%5Ctimes%20side%20%5Ctimes%20side%29%7D%7D%20%5C%5C%20%7B%20%5Ctt%7Bv%20%3D%20%28s_%7B1%7D%20%5Ctimes%20s_%7B2%7D%20%5Ctimes%20s_%7B3%7D%29%20%7D%7D)
since sides of a cube are identical:
![{ \sf{s_{1} = {s_{2} = {s_{3}}}}}](https://tex.z-dn.net/?f=%7B%20%5Csf%7Bs_%7B1%7D%20%3D%20%7Bs_%7B2%7D%20%3D%20%20%7Bs_%7B3%7D%7D%7D%7D%7D)
Therefore:
![{ \sf{volume = (250 \times 250 \times 250) \: mm {}^{3} }} \\ { \sf{v =15,625,000 \: {mm}^{3} }}](https://tex.z-dn.net/?f=%7B%20%5Csf%7Bvolume%20%3D%20%28250%20%5Ctimes%20250%20%5Ctimes%20250%29%20%5C%3A%20mm%20%7B%7D%5E%7B3%7D%20%7D%7D%20%5C%5C%20%20%7B%20%5Csf%7Bv%20%3D15%2C625%2C000%20%5C%3A%20%20%7Bmm%7D%5E%7B3%7D%20%20%7D%7D)
but 1 mm³ = 0.000001 cm³
![{ \sf{v = (15,625,000 \times \{1 \times {10}^{ - 6} \} ) \: cm}} \\ { \sf{v = 15.625 \: {cm}^{3} }}](https://tex.z-dn.net/?f=%7B%20%5Csf%7Bv%20%3D%20%2815%2C625%2C000%20%5Ctimes%20%20%5C%7B1%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%206%7D%20%5C%7D%20%29%20%5C%3A%20cm%7D%7D%20%5C%5C%20%7B%20%5Csf%7Bv%20%3D%2015.625%20%5C%3A%20%20%7Bcm%7D%5E%7B3%7D%20%7D%7D)
Angles 1 and 4 are alternate angles and thus have the same measurement. You will set their equations equal to each other and solve for the variable.
6n + 1 = 4n + 19
Subtract 1 and 4n from both sides to get variables on one side and constants on the other.
6n - 4n = 19 - 1
Combine like terms and solve for n.
2n = 18
n = 18 / 2
n = 9
Angles 1 and 2 are congruent as labeled in the graph.
So angle 2 is also 6n + 1
Plug in for 9 for n
6(9) + 1
54 + 1
55
Option C is your answer.
