Question

You're sitting on the ledge of a wall that is 300 feet away from a building. You have to

Answer 1

The total height of the building in question is;

600 ft

Angle of Elevation

The ledge of a wall is simply a projection from a building.

Now, we are told that this ledge is 300 ft from the building.

• Angle of elevation to the building top = 60°
• Angle of depression to the building bottom = 15°

Now, from the attached image, the distance from the ledge on the building wall to the top of the building is x.

• Thus, by trigonometric ratio;

x/300 = tan 60

x = 300 × 1.732

x ≈ 520 ft

• Similarly, via trigonometric ratio;

y/300 = tan 15

y = 300 × 0.2679

y ≈ 80

Thus;

Height of building = 520 + 80

Height of building = 600 ft
