Answer:
18m away / 45° inclination.
Let the height of pole be h m
so AB=hm
Distance of the point from
base of pole = 18m
CB=18m
Angle of elevation =45 °
∠ACB=45°
Since tower is vertical to ground
∠ABC=90°
Now tanC= side opp to angle C
___________________
side adjacent to angle C
tanC= AB/CB
tan45= AB/CB
1= H/18
H= 18
Hence height of tower = 18m
