Question

A vertical pole 10m long casts a shadow √3 long. At the same time tower casts a shadow 90m long. Determine the height of the tower.

​

Answer 1

Answer:

Same time gives us same angle then,

Length of pole=10m,pole shadow length=√3,

tan=10/√3 ---equation 1

Now,

Length of tower shadow=90m, length of tower=?

tan =?/90 ---equation 2

From the equation 1and2we have,

10/√3=?/90

10×90/√3=?

10×30√3=?

300√3=?

Then,the height of tower=300√3m
