Intuitively, the answer is 3, but to confirm, remember that the constant of proportionality k is y/x,
y = 3x Divide both sides by x
y/x = k = 3
Thee constant of proportionality is B) 3
the percent is 130% for the question
No the angle of each piece should be 60 degrees, if the three pieces were to be 25 each that would only add to 75
You use tan34=x/15
so x=15*tan(34degrees)
x=10.12 ft
