Question

OA= a and OB = b.
(a) Express BA in terms of a and b.
(b) Given that BX = mBA, show that OX = ma + (1 – m)b
(c) Given that OP = 4a and PQ = 2b, express OQ. in terms of a and b.
(d) Given that OX = nOQ use the results for OX and OQ to find the values of m and n.

Answer 1

Answer:

a) OA+OB=AB

so,

AB= a+b
