A pyramid shaped building is 311 feet tall and has a square base with sides of 619 ft. The sides of the building are made from r
zmey [24]

Answer:

Surface area of the reflective glass is 543234.4 square feet.

Step-by-step explanation:

Given that: height = 311 feet, sides of square base = 619 feet.

To determine the slant height, we have;

l^{2} = 311^{2} + 309.5^{2}

   = 96721 + 95790.25

   = 192511.25

⇒ l = \sqrt{192511.25}

      = 438.761

The slant height, l is 438.8 feet.

Considering one reflecting surface of the pyramid, its area = \frac{1}{2} × base × height

  area =  \frac{1}{2} × 619 × 438.8

          = 135808.6

          = 135808.6 square feet

Since the pyramid has four reflective surfaces,

surface area of the reflective glass = 4 × 135808.6

                                                          = 543234.4 square feet

An observer (O) is located 500 feet from a school (S). The observer notices a bird (B) flying at a 39° angle of elevation from h
Serhud [2]

Answer:

h=404.89

Step-by-step explanation:

We are looking for side h, which is opposite of the observer. We know that the side adjacent to the observer is 500 feet. We also know that the angle from the observer to the bird is 39°. Because we have these values, SOH CAH TOA tells us that we should use tangent, opposite over adjacent.

We can set up our equation as follows:

tan(39°)=h/500

We can then solve for h:

500*tan(39°)=h

h=404.89
