You fly a hot air balloon 0.5 miles above the ground. What is the measure of BD⌢, the portion of Earth that you can see? Round y
salantis [7]

Step-by-step explanation:

To solve this problem, we need the angle CAD, which can then be used to calculate the arc BD.

From definition of cosine,

cos(x) = adjacent / hypotenuse

cos(x) = AD / AC = 4000 / 4000.5 = 0.9998750156230471

The inverse function gives

x = arccosine (4000/4000.5)

  = arccosine (0.9998750156230471)

  = 0.01581056485742214 radians = 0.9058786380481468 degrees

Radius of the earth, r = 4000 miles

Arc BD = 2 time arc subtended by angle x

= 2 (rx)    where x is in radians

= 2*4000*0.01581056485742214

= 126.48 miles (to two decimal places)

velikii [3]

Answer:

\theta=cos^{-1}(\frac{2}{3})

Step-by-step explanation:

We are given that measurements of three points on the ground gave coordinates of (0,0,0),(1,2,0) and (0,2,1)

We have to find the angle by which the tower now deviate from the vertical

We find cross product of <1,2,0> and <0,2,1>

\times =\begin{vmatrix}i&j&k\\1&2&0\\0&2&1\end{vmatrix}

\times =2\hat{i}-\hat{j}+2\hat{k}

Now, we are finding the angle between  \timesand vertical vector <0,0,1>

Angle between two vectors formula

cos\theta=\frac{a.b}{\mid a\mid\cdot\mid b\mid }

Now, using this formula

cos\theta=\frac{2}{1\cdot 3}=\frac{2}{3}

\theta=cos^{-1}(\frac{2}{3})

Hence, the tower deviate from the vertical by the angle \theta=cos^{-1}(\frac{2}{3})
