Answer:
a protractor
Step-by-step explanation:
You measure a straight line with a ruler
You measure an angle with a protractor
192 is the answer definately
Answer:
(-4,0)
Step-by-step explanation:
We start at the origin (where the lines cross)
We will go left 4 units. That is the x coordinate (-4)
We go up 0. That is the y coordinate
(x,y)
C = (-4,0)
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

(The picture explains it, if you dont understand, sorry but it's kinda hard to explain. I hope it helped.)
