as we know that, 1'=60''=>1''=(1/60)'.
and 15''=(15×1/60)'=(1/4)'
again, we know that 1°=60'=>1'=(1/60°)
so (1/4)'=(1/240)°. =(1/240×π/180)c.
let the angle between the man and the ground be x°. then tan(π/43200)=167.64/h=>.000072=167.64/h=>h=2328333cm.
(approx).where h is the distance from the man to the angle.

Distance a man of height 5.5feet subtend an angle of 15"
Step-by-step explanation:
- By the help of fig tan
- 15 = 5.5 / x =
- 2679 5.5 / x
- x = 5.5 / 2679 = x = 20.53ft.
