First, change the measurements of the pole to m so all of the units are the same.
41 cm=.41 m
72 cm=.72 m
Then, let x represent the height of the building
30/x=.72/.41
x=30*.72/.41
x=52.68 m
round to 52.7 m
Answer:
see explanation
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 = 
( multiply both sides by 9 )
k = 135
y = 
← equation of variation
