(i) Distance RT = (7m - 3m) = 4m
(ii) Distance of the foot of the taller pole from P = 20m + 3m = 23m, correct to 3s.fs.
(iii) Angle of elevation of T from P = 30° + 30° = 60°, correct to 1d.p.
The feet of two vertical poles of heights 3metres and 7metres are in line with a point P on the ground, the smaller pole being between the taller pole and P at a distance 20metres from P. The angle of elevation of the top (T) of the taller pole from the top (R) of the smaller pole is 30◦. Calculate the: (i) distance RT (ii) distance of the foot of the taller pole from P, correct to 3s.fs. (iii) angle of elevation of T from P, correct to 1d.p.
