Answer:
a
[tex]\= HK = \= t + \= u[/tex]
b
[tex]\= GL = \= s - \= t[/tex]
c
[tex]\= JH = \= u + \= s[/tex]
Step-by-step explanation:
Now looking at the diagram
Following the direction of the unit vectors [tex]\= u , \= s, \= t[/tex]
[tex]\= {HK} = \= {KI} + \= KL[/tex]
=> [tex]\= HK = \= t + \= u[/tex]
And
[tex]\= GL = \= GH + \= GF[/tex] jjj
=> [tex]\= GL = \= s - \= t[/tex]
Also
[tex]\= JH = \= JG + \= JI[/tex]
=> [tex]\= JH = \= u + \= s[/tex]
