Need to find the direction angle for each vector. #10 and #12 please!
crimeas [40]

Answer:

10)  - 45 degrees

12)  0 degrees

Step-by-step explanation:

10)

Find the x and y components that define the vector that joins C with D:

x-component: -4 - (-8) = - 4 + 8 = 4

y-component:  4 - 8 = -4

use the tangent function to find the angle \theta:

tan(\theta)=\frac{y-comp}{x-comp}=\frac{-4}{4}  = -1\\\theta = -45^o

12)

Find the x and y components that define the vector that joins A with B:

x-component: 7 - 4 = 3

y-component:  - 1 - (-1) = -1 + 1 = 0

use the tangent function to find the angle \theta:

tan(\theta)=\frac{y-comp}{x-comp}=\frac{0}{3}  = 0\\\theta = 0^o

On the rectangular coordinate system, what is the shortest distance between points (−4, 3) and (−2, −1)?
pogonyaev
Shortest Distance = \sqrt{ (-4+2)^{2} + (3+1)^{2} }
Shortest Distance = \sqrt{ (-2)^{2} + (4)^{2} }
Shortest Distance = \sqrt{20}
Shortest Distance = 4.47 units
