1.	A flag is standing vertically on a tower of height b. On a point at a distance a from the foot of the tower, the flag and the tower subtend equal angles. The height of the flag is(a) b. \(\frac{a^2+b^2}{a^2-b^2}\)(b) a. \(\frac{a^2-b^2}{a^2+b^2}\)(c) a. \(\frac{a^2+b^2}{a^2-b^2}\)(d) b. \(\frac{a^2-b^2}{a^2+b^2}\)
Answer» (a) b. \(\frac{a^2+b^2}{a^2-b^2}\)
