If distance between two pillars of length 9 & 4 cm is x
If distance between two pillars of length 9 & 4 cm is x
cm. If two angle of elevation of their respective top from a point on ground of other are complementary to each other, then value of x is
Let A and B are the angles of elevation of given 2 pillars As we know that tan A x tan B = 1 when A and B are complementary angles (4/x) X (9/x) = 1 x2 = 36 x = 6 cm More Height and Distance Questions
