0
Hence the answer is 0. : Answer
Hope it will help :)
Answer:
This statement is true for any N vectorial space.
By definition u·v=|u|·|v|·cos(α), where α is the angle between u and v.
If -1≤cos(α)≤1, we can assume:
|u·v|=||u|·|v|·cos(α)|=|u|·|v|·|cos(α)|≤|u|·|v|
Answer:
x = 8°
Step-by-step explanation:
(7 x + 1) + (3 x +9) = 90
10 x + 10 = 90
10 x = 80
x = 8°
