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

Answer:

5 feet below the sea level.

Step-by-step explanation:

Helene, a hiker starts at an elevation of 27 feet above the sea level.

Then Helene descends 32 feet that means her total elevation above the sea level will be

h = 27 - 32 = -5 feet.

Minus sign indicates that Helene is 5 feet below the sea level.
