um if you could check 9 and then through from 12-19 would be good
7 should be B
8 should be A
and 9 should be C
forgot to check that

um for 10? just made a triangle and found hypotenuse?

7 should be B
8 should be A
and 9 should be C

agreeded for 7 and 8, think again about 9..

hint - if you deduct a vector, it's the same as adding one of the opposite direction
