Answer:
48'11'' or 587''
Explanation:
First convert to inches
5ft= 12 times 5 = 60 then plus 6=66in.= Jen's height
The ratio of the Jen height to Jen's shadow heightis 5'6'' : 9' which is equal to 66in.:108in.
To find the ratio we do 108/66 = 1.636...
Then we do 80' which is equal to 960"
Lastly we do 960/1.636... to get 586.797in for the height of the tree
48'11'' or 587''
