Answer:
Step-by-step explanation:
If θ is the angle between two vectors u and v, then cosθ = (u·v) / [llull llvll]
u·v = (8)(9) + (7)(7) = 121
llull = √[(8)2 + (9)2] = √145 llvll = √[(7)2+(7)2] = 7√2
So, cosθ = 121/ [7√290]
= 1.015052094
θ = Cos-1(1.015052094) ≈ 3.3

Incase your wondering what happened to the y it got canceled out because they were equal on both sides.
Hello :D
To work this out we need to look at the thousands column. After you find the thousands column, you look at the column on the right side of it. If that number is higher than 5, you round it up. If it is 4 or lower, then you round it down.
990687
Thousands = 0687
It has a 6 next to it you round it up. So the answer would be 991000. I hope this helps
