From the top of a vertical mast 150m high., two huts on the same ground level are observed. One due east and the other due west of the mast. Their angles of depression are 60° and 45° respectively. Find the distance between the huts
150(1 + √3)m
50( √3 - √3)m
150 √3m
50√3m
Correct answer is B
150Z = tan 60o,
Z = 150tan60o
= 1503
= 50√3cm
150XxZ = tan45o = 1
X + Z = 150
X = 150 - Z
= 150 - 50√3
= 50( √3 - √3)m
