I understand how to do to the first question- it’s 6b-6aLet's focus on (a)(i). Draw a figure with just O, A, and B, and with arrows showing OA, OB, and AB. Look to see if any two of these add up to the other (that is, they go head to tail). Write an equation that expresses that sum, and solve for AB. (With experience, you would be able to write the answer immediately, but not yet!)
For the other parts, you are probably expected to use some knowledge of which parts of a regular hexagon are parallel or congruent, but we'll get there.
To Fudge111211111, This appears to be from the same source as the question on combinatorics. If I were you I would find myself a more up-to-date set of questions. As to the above vector question, there is not one standard bit of notation about it. You are not preparing yourself for real university study by using faulty material.View attachment 16821
I Don’t know how to get the answer for these 3 questions. Guidance needed please
