Helene, a hiker, starts at an elevation of 27 feet above sea level and descends 32 feet during her hike to base camp. Which describes the elevation of base camp?

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
