An engineer is undertaking some reconnaissance by pacing on a construction site. the engineer takes 26 steps per 20m, the ground he is walking on has a vertical slope angle of 6. the engineer takes 152 steps. how far has he travelled horizontally (in enter numeric answer to 2 decimal places, no alpha characters)

116.28m

Explanation:

First, if you see the diagram below, you notice that the slope is measured in steps, and you need to change it to meters:

Then, use the cos function because it can relate the hypotenuse and the adyacent side of the triangle:
