C is the correct answer I worked it out
45 45 90 triangle
Ratio of leg : hypo = x : x√2
Given hypo x = 5
So leg = 5/ √2 = 5√2 / 2
Answer
A. 5√2 / 2
This is ur answer… see the image i attached
Lets say a balloon = x
4x + 5x + 6x = 120
15x = 120 (divide each side by 15)
15x/15 = 120/15
x = 8
blue balloons = 4x = 4(8) = 32
red balloons = 5x = 5(8) = 40
yellow balloons = 6x = 6(8) = 48
