Question

a flag pole of 7m tall costs a 8m shadow at the same time a nearly bulding casts a shadow of 32mts how tall is the bulding? ​

Answer 1

7m pole have 8 m shadow

so when the height of pole increase then shadow also increase

hence it is direct proportion

7/8=x/32

x=building height=7*32/8

x=building height=28 m

Answer 2

Tan theta = perpendicular/ base

Tan theta = 7/8 ( given for pole)

Sunlight angle would remain same

So, tan theta =height of building/ 32

7*32/8 = height of build.

Height = 28 m
