Math Problem Statement

The angle of elevation to the top of a Building in New York is found to be 5 degrees from the ground at a distance of 1 mile from the base of the building. Using this information, find the height of the building. Round to two decimal places. Hint: 1 mile = 5280 feet

Solution

We can solve this problem using trigonometry, specifically the tangent function, since we have an angle and the opposite and adjacent sides of a right triangle.

Given:

  • Angle of elevation = 55^\circ
  • Distance from the base of the building = 11 mile = 52805280 feet
  • Height of the building = hh (to be found)

Using the tangent function: tan(θ)=oppositeadjacent\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} tan(5)=h5280\tan(5^\circ) = \frac{h}{5280}

Now, solving for hh:

h=5280×tan(5)h = 5280 \times \tan(5^\circ)

Let's calculate: math

Given values

theta = 5 # degrees distance = 5280 # feet

Calculate height using tangent function

height = distance * math.tan(math.radians(theta)) round(height, 2)The height of the building is 461.94 feet when rounded to two decimal places.
