Ye, but you need to know if there are any parallel sides, and angles help u tell this....
the pic doesnt give much....ther has to be more....

a) AB
Answer = y - x. Because AO = - x and OB = + y
b) AM
Answer = 1/2(y-x). Because AM = 1/2 AB
c)OM
Answer = OM
= OA + AM = (x) + 1/2(y-x) = 1/2(y+x)
I got a blackbelt in Maths/Physics... Oops, I meant degree! :up:

oh cool
this is what the question says:
In questions 1-10, each vector should be expressed in terms of x and y, where AO =x and OB =y.
1)
M is the mid-point of AB
Find:
a) AB
b) AM
c)OM
and the picture is below it

Can't figure out if it's a right angled triangle or a scalene traingle.
Can you post the numbers up sis?
I think only one side is parallel but i'm not sure, the pic is hazy.

I dont know what number ur talking about :confused:
do u mean angles?
vectors dont have angles, well according to the vectors im doing :o
the triangle is a scalene
:jkk: for ur concern
by the way, im a brother not a sister :)

Sounds right to me.
