Answer:

The actual height of the observation deck is 1206.82 ft

Step-by-step explanation:

Let h be the height of the building

And d be the height of the observation deck

Therefore,

d/h = 8.3/10 = 0.83

d = 0.83h

Given that h = 1454 ft

d = 0.83 × 1454 ft

d = 1206.82 ft

To compare two whole numbers to find a percent, divide the first number by the second number:

224/640 = 0.35.

Multiply the dividend by 100 to get a percent.

0.35 x 100 = 35%.</span></span></span></span></span></span>

To the nearest hundredth, what is the value of x?
timofeeve [1]

Answer:

The answer to your question is x = 37.74

Step-by-step explanation:

Data

Right triangle

hypotenuse = c = 45

angle = 33°

adjacent side = x

Process

To solve this problem use trigonometric functions. The trigonometric function that relates the adjacent side and the hypotenuse is cosine.

               cos Ф = Adjacent side / Hypotenuse

-Solve for Adjacent side

               Adjacent side = hypotenuse x cosФ

-Substitution

               Adjacent side = 45 x cos 33

-Simplification

              Adjacent side = 45 x 0.839

-Result

            Adjacent side = x = 37.74
