The height of radio tower is 576 feet approximately
<em><u>Solution:</u></em>
Given that, radio tower casts a shadow 8 feet long
At the same time that a vertical yardstick casts a shadow half an inch long
To find: height of radio tower
Let "x" be the height of radio tower
length of shadow of tower = 8 feet
Length of shadow of stick =
Convert inch to feet
Thus,
Length of shadow of stick = 0.0416 feet
Length of vertical yard stick = 3 feet (since 1 yard = 3 feet )
Therefore, by proportion we get,
Substituting the values we get,
Thus height of radio tower is 576 feet approximately
