Let AB be the flag pole and let C be the point where the man is standing.
CD is the height of the man.
∠ADE is the angle of elevation = 28˚
∠BDE is the angle of depression = 13˚
Let AE = h m and EB = x m, ED = BC = 9 m
In ∆ADE, ∠ADE =28˚, DE = 9 m, and AE = h m
 
Height of the pole = AE + EB = h + x = 6.87 m
