If <1 is 37 what is the measure of <8?

djyliett [7]

Answer:

<8 = 37

Step-by-step explanation:

Diagonal angles are equal, so <1 = <4

Angles on parallel lines intersected by the same line are equal too, so <4 = <8

Since <1 = <4 and <4 = <8, you can assume that <1 = <8, therefore <8 = 37

Answer:

w= 12

Step-by-step explanation:

2w=24

divide both sides by 2

A million years ago, an alien species built a vertical tower on a horizontal plane. When they returned they discovered that the

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