Question

An electric pole, 21 metres high, casts a shadow of 15 metres. Find the height of a tree casts a shadow of 20 metres under similar conditions.

Answer 1

Answer:

32m

h1 = 20m

b1 = 15m

h1/b1 = 20/15 = tan θ (opp/adj )

=> h2/b2 also equals 20/15

=> h2/24 = 20/15

=> h2 = (20/15) * 24

= 32m
