22 Three tourists T₁, T2 and T3 at ground level are observing a landmark whose top we shall call L. T₁ is due north of L, T3 is due east of L, and T, is on the line of sight from T₁ to T3 and between them. The angles of elevation to the top of L. from T₁, T2 and T3 are 25°, 32° and 36° respectively. a Show that tan
