Help with this M1 question

Its on Vectors. I don't understand how to do part c even after seeing the mark scheme.

Can anyone help?

Thank you

if it's due NE wouldn't the angle be 45 degrees?

Edit: sorry this is all i can suggest I actually hate vectors with a passion

If R is NE of S what does that tell you about the vector r-s ?

Would that take me to the origin?

im assuming you;ve dine parts a and b.
From b use your equations to find an expression for R - S

If the angle is 45 degrees that tells you that tan(45) = 1

so j/i will equal 1. (components)

Carry this out for your expression of R - S and solve for T.
