Ex 6.3, 15 A vertical pole of length 6 m casts a shadow 4 m long on the ground and at the same time a tower casts a shadow 28 m long. Find the height of the tower. Given: Height of pole = AB = 6m Length of pole of shadow = BC = 4 m Length of shadow of tower = EF = 28 To Find : Height of tower i.e ED Solution:- In β π΄π΅πΆ and β π·πΈπΉ β B = β E = 90Β° β πΆ=β πΉ β΄ β π΄π΅πΆ βΌ β π·πΈπΉ β π΄π΅πΆ βΌ β π·πΈπΉ We know that if two triangles are similar, ratio of their sides are in proportion So, π΄π΅/π·πΈ=π΅πΆ/πΈπΉ 6/π·πΈ=4/28 6 Γ28=π·πΈΓ4 (6 Γ 28)/4= π·πΈ 6 Γ7=π·πΈ π·πΈ = 42 Hence, the height of the tower is 42 metres
