Question

The angle of elevation of the top C of a vertical tower CD of height h from a point A in the horizontal plane is 45°
and from a point B at a distance from A on the line making an angle 30° with AD in the vertical plane it is 60°
then angle CBA = k.50 (in degrees). The value of k is​

Answer 1

Answer:

The angle of elevation of the top C of a vertical tower CD of height h from a point A in the horizontal plane is 45°

and from a point B at a distance from A on the line making an angle 30° with AD in the vertical plane it is 60°

then angle CBA = k.50 (in degrees). The value of k is​ 2
