Answer:
20 feet
Step-by-step explanation:
Consider the given pictorial representation below,
The Height of the Pole =|AB|
The Height of the Person =|DE|
Shadow cast by the Pole =|AC|
Shadow cast by the Person =|EC|
Triangles ABC and DEC are similar triangles therefore,
Cross multiplying
x X 1.5 = 6 X 5
x=30/1.5 =20 feet
Height of the flag pole = 20 feet
