Take the dot product, if the dot product is zero, they are orthogonal
<span>the dot product here is 15(-5) + 45(12) so the vectors are not orthogonal </span>
<span>to see if they are parallel, take the dot product again, using the definition </span>
<span>u dot v = mag u x mag v cos (theta) where mag is the magnitude of the vector and theta is the angle between them </span>
<span>we know from above that u dot v = 465 </span>
<span>mag u = sqrt[15^2+45^2]=47.43 </span>
<span>mag v = sqrt[5^2+12^2]=13 </span>
<span>so we know: </span>
<span>cos(theta) = 465/(47.43x13) = 0.75 </span>
<span>
so theta = 41 deg</span>
Answer:
7.22
Step-by-step explanation:
3.49+7.50+1.79= 12.78
20.00 -12.78=7.22
Answer:
1
Step-by-step explanation:
Hopefully this is correct. say your starting point is {B} and want to go to {A}. clockwise is always to the left and the mark {B} is on a 90 degree angle both ways. so you would need to go 90 degrees clockwise to get around to A.
I am just a middle schooler hopefully this piece of information may help you figure it out.
