<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>

Answer:
7, you can just your calculator to test it out.
Answer:
2: 86
3:64
4: 77
6: 3
7:12
8: O=110 X:110
Step-by-step explanation:
Number 2 shows what is called a central angle. Central Angles are equivalent to the ark length
Number 3 shows an Inscribed angle. These angles are half of the ark but in your question, it is twice the angle measurement
Number 4 you want to divide the ark length by two when the angle is not given. And when the angle is given you want to mutilate by two
Number 6 is Overlapping Ark which means they are both congruent to each other because the ark is equivalent to each other.
Number 7 is x=12 because 5x+12 is twice the measure of 3x
Number 8 o=110 because a circle has 360 degrees so you want to add them up and then subtract that from 360. x is also 110 degrees because it is a central angle, which is the same amount of degrees as the ark length.
Answer:
I think it's 14
Step-by-step explanation:
Hello!
4*a (2)= 8 and 8-2 equals to 6. 8 + 6 is 14.
Have a good day.
