A man 1.9m tall observes the angle of elevation of the top and bottom of a mast as 65° and 41° respectively.If the mast is mounted on a house 12m tall,find correct to 3 significant figures
I.distance of the man from the house
ii.length of the mast
As always, draw a diagram, and review your basic trig functions.
(i) (12-1.9)/x = tan41°
(ii) (h+12-1.9)/x = tan65°
