P and Q are two observation posts on the same horizontal ground as the foot R
of a vertical pole RT. P is 2.5 km south
of R. Q is east of R and is on a bearing
of 065° from P. The angle of elevation
of T from P is 40°. Calculate, correct to
three significant figures:
i) sketch the diagram
ii) the distance RT
iii) the distance RO
iv) the distance PQ
v) the angle of elevation of T from Q.​

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
