How tall is this oak tree?
Your friend is trying to calculate the height of a nearby oak tree. You tell him that you learned how to use similar triangles in Geometry class. You tell your friend to measure his height (75 inches) and you measure the length of his shadow (48 inches). Both of you measure the length of the tree’s shadow (38 feet). How tall is the tree (in feet)? Round to the nearest hundredth.
If “x” is the height of the tree in feet :
75 / 48 = x / 38
Note : you don’t have to convert in feet or in inches because it is a ratio and you will have in/in and ft/ft.
x = (75 * 38) / 48
x = 59.375 feet
To the nearest hundredth, height is 59.38 feet
