Answer:
15√2 (fourth answer choice)
Step-by-step explanation:
Note that the ratio 15/x is the tangent of 30 degrees, which in turn is 0.577 or 1/√2. Then:
1/√2 = 15/x, or
1 5
----- = ----- or x = 15√2
√2 x
R + g + b = 50
r = b + 6
g = b - 4
(b + 6) + (b - 4) + b = 50
3b + 2 = 50
3b = 50 - 2
3b = 48
b = 48/3
b = 16 <=== 16 blue marbles
r = b + 6
r = 16 + 6
r = 22 <=== 22 red marbles
g = b - 4
g = 16 - 4
g = 12 <=== 12 green marbles
