Question

18) At noon, what is the length of the shadow cast by a flagpole known to be 20 feet tall? Label the answer correctly.

Answer 1

   Actual length of the pole and the length of the shadow cast by the pole follow the proportional relationship.

Following this rule, 20 feet tall flagpole will cast 3.33 feet shadow.

  If the length of the shadow = x feet

Proportional relationship will be defined by the expression,

$\frac{\text{Actual height}}{\text{Length of the shadow}}\rightarrow \frac{6}{1}= \frac{20}{x}$

$6x=20$

$x=\frac{20}{6}$

$x=3.33$ feet

   Therefore, length of the shadow cast by flagpole will be 3.33 feet.
