Answer» Answer: Mall is 500 m TALL Step-by-step explanation: Guddi was standing on a ROAD NEAR a mall. She was 1000m away from the mall and able to SEE the top of the mall from the road in such a way that top of the tree, which is in between her and the mall, was exactly in line of sight with the top of the mall. The tree height is 10m and it is 20m away from Guddi. Tan θ = Perpendicular / Base Angle with tree top & Mall top is same Tanθ = Height of tree / Distance of tree from guddi => Tanθ = 10/20 => Tanθ = 1/2 Tanθ = Height of Mall / Distance of Mall from guddi => 1/2 = Height of Mall / 1000 => Height of Mall = 500 m Mall is 500 m Tall |
