Explanation of Solution
Given:
the height of the steeple and the angles of elevation to D and A are
Concept used:
Calculation:
The figure can be drawn as a right-angled triangle as shown below.
Where AD is the height of the steeple and the angles of elevation to D and A are
Use the fact that BC=50 ft.
In the right angle
For the larger triangle use the fact that in the right
Now the height of steeple is given as
Therefore, the height of the steeple is 19.89ft.
