Diagram below shows three vertical poles JP, KN and LM, on a horizontal plane.
The angle of elevation of N from P is 15o.
The angle of depression of M from N is 35o.
Calculate the distance, in m, from K to L.
Diagram below shows two vertical poles JM and LN, on a horizontal plane.
The angle of elevation of M from K is 70oand the angle of depression of K from N is 40o.
Find the difference in distance, in m, between JK and KL.
