Answer 1

Answer:2.5 m

Explanation:LET AB BE A BOY = 1.5 M

CD BE A LAMP = LET IT BE X M

OB BE THE SHADOW CAST BY BOY = 4.5 M

BD BE DISTANCE BETWEEN BOY AND LAMP = 3 M

THEREFORE, IN TRIANGLE AOB, TAN THETA = AB/OB

IN TRIANGLE COD, TAN THETA = CD/OD = CD/(OB+ BD)

•°• AB/OB= CD/(OB+BD)

1.5/4.5=CD/(4.5+3)

CD= 7.5/3= 2.5 M
