Answer:

15/2 sqrt(3) =z

15/4 sqrt(3) =y

Step-by-step explanation:

cos theta = adjacent side/ hypotenuse in a right triangle

cos 30 = z / 15

Multiply each side by 15

15 cos 30 = z

15 ( sqrt(3)/2)

15/2 sqrt(3) =z

sin theta = opposite side/ hypotenuse in a right triangle

sin 30 = y / z

Multiply each side by z

z sin 30 = y

z (1/2)=y

Z = 15/2 sqrt(3)

15/2 sqrt(3)*1/2

15/4 sqrt(3) =y

Given A(2, 3) B(1, 4) C(1, 3) D(-2, 2). How are AB and CD related?

kondaur [170]

The vector AB is not related with the vector CD as k is not the same for each pair of components.

<h3>Are two vectors similar?</h3>

In this question we must prove if the vector AB is a multiple of the vector CD, that is:

$\overrightarrow{AB} = k \cdot \overrightarrow {CD}$

$\vec B - \vec A = k \cdot [\vec D - \vec C]$

(1, 4) - (2, 3) = k · [(- 2, 2) - (1, 3)]

(- 1, 1) = k · (- 3, - 1)

Hence, the vector AB is not related with the vector CD as k is not the same for each pair of components.
