Find the angle between each vector pair. WX with W(3,-1) and X(5,-2)
YZ with Y(2, 9) and Z(-2,3)

I know that you use cos^-1 to find (theta) but that is it...​

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
