Question

the angle of depression of the top of a pole 7 m from the top of a building is 60 degree and the angle of depression of the foot of the building on the top of the police 45 degree find the height of the building and and the distance between the building and the pole​

Answer 1

EC=DE+CD

CD=AB=7 m and BC=AD

In △ABC,

tan45°=BC/AC=AD/CD

BC=7×1 m =AD=7 m

AD=CD=7 m

In △ADE

tan60°= AD/DE=CD/DE

DE=7=√3m

Height of tower =EC=DE+CD

=(7√3+7) m

=7(√3+1) m
