To determine the elevation of point B on top of a cliff, the transit is set up at point A with an elevation of 41.2 m. The vertical angle to point B was +16°32' and the height of instrument is 1.5 m. The transit is transferred to a point E at a horizontal distance of 60 m from A, the new vertical angle was +24°28'. Finally with the telescope horizontal, the reading on the stadia rod at A was 1.84 m. What is the elevation of point B?
