Using the three trigonometric functions can be used to calculate unknown side lengths and angle in a right-angle triangle only.
But, if ever you we're given to find a non right-angle triangle, you will have to use sine rule or cosine rule.
18.725 = 18725/1000 = 3745/200 = 749/40 = 18 29/40
so, your answer is 18 29/40
The ground level is to be the zero level. When the elevator moves above the ground level, it is moving towards the positive integer and when the elevator moves below the ground level, it is moving towards the negative integer.
Elevator 2 moved down 6 feet from the ground level hence its position is labelled as
