Building A is 50 .34 ft taller than building B
The situation forms a right angle triangle.
Two right angle triangles are formed.
Right angle triangle:
Right angle triangle has one of its angle as 90 degrees.
Therefore, trigonometric ratios can be used to find the sides of the building.
The height of the buildings is the opposite sides of the triangle formed. The adjacent sides is the distance from the building to the person.
Therefore,
Building A;
- tan 40 = opposite / adjacent
- tan 40° = h / 120
- h = 100.691955741
- h = 100.69 feet
Building B:
- tan 40 = h / 60
- h = 50.3459778706
- h = 50.34 feet
Therefore, building A is around 50.34 ft taller than the building B
