Question

.
A flagpole stands 12 ft. tall. It casts a shadow that is 8 ft. long. What is the length from the tip of the flagpole to the tip of its shadow? Round your answer to the nearest tenth.

Answer 1

using the Pythagorean theorem 

c^2 = a^2 +b^2
C^2 = 12^2 + 8^2
c^2 = 144 +64
c^2 = 208

c= sqrt(208)

c= 14.4 feet
