Two persons are 'a' meters apart and the height of one is double that of the other, if from the middle point of the line joining their feet, an observer find the angular elevation of their tops to be complementary then the height of shorter person is :

Two persons are 'a' metres apart and the height of one is double that of the other. If, from the middle point of the line joining their feet, an observer finds the angular elevation of their tops to be complementary, the height of the shorter person in metre is _______ .

Two persons are 'a' metres apart and the height of one is double that of the other. If from the middle point of the line joining their feet, an observer finds the angular elevation of their tops to be complementary, then the height of the shorter post is (a) a/4 (b) a/(sqrt(2)) (c) asqrt(2) (d) a/(2sqrt(2))

Two persons are a metres apart and the height of one is double that of the other. If from the middle point of the line joining their feet, an observer finds the angular elevation of their tops to be complementary, then the height of the shorter post is a/4 (b) a/(sqrt(2)) (c) asqrt(2) (d) a/(2sqrt(2))

Two persons are a metres a part and the height of one is double that of the other. If from the middle point of the line joining their feet, an observer finds the angular elevation of their tops to be complementary then the height of the shorten post is____

Two poles are a metres apart and the height of one is double of the other. If from the middle point of the line joining their feet an observer finds the angular elevations of their tops to be complementary, then the height of the smaller is (a) sqrt(2)am e t r e s (b) a/(2sqrt(2))m e t r e s (c) a/(sqrt(2))m e t r e s (d) 2am e t r e s

Two vertical poles are 120 metres apart and the height of one is double that of the other. From the middle point of the joining their feet, an observer finds the angular elevations of their tops to be complementary . Find the heights of the poles.

Two poles are a metres apart and the height of one is double of the other.If from the middle point of the line joining their feet an observer finds the angular elevations of their tops to be complementary,then the height of the smaller is sqrt(2)a metres (b) (1)/(2sqrt(2)) metres (a)/(sqrt(2)) metres (d) 2a metres

Two posts are x meters apart and the height of one is double that of the other. If from the mid-point of the line joining their feet, an observer finds the angle of elevations of their tops to be complementary, then the height (in meters) of the shorter post is दो खंभे एक दूसरे से xमी दूर है तथा एक खंभा दूसरे का दो गुणा था। अगर उनके पायों को जोड़ने वाली रेखा के मध्य बिन्दू पर खड़ा एक प्रेक्षक उनके उन्नयन कोण पूरक पाता तब छोटे खंभे की ऊँचाई बताइये।
