Question

The angle of elevation of the top of a vertical tower from a point on the ground is 60degere from another point 10th vertically above the first it's angle of elevation is 45 degree find the height of the tower

Answer 1

let height of tower be h and dist from point on grnd to tower b. then h/b = tan 60. for the second point 10 above the first (h-10)/b=tan 45. solving these eqns h=23.66 m
