This is the concept of application of trigonometry, the question requires us to get the angle of elevation. The angle of elevation will be given by:
sin theta=[opposite]/[hypotenuse]
opposite=27ft
hypotenuse=32 ft
Thus;
sin theta=27/32
hence;
theta=arcsin (27/32)
=57.54
The answer is, the angle of elevation was 57.54 degrees
