Step-by-step explanation:
i)
height of pole above eye level = 10-2=8m
from triangle,
tan x = 2/5 = opposite side / adjacent side
that is,
2y/5y = 8/AB
AB= (8×5)/2
AB = 20 m
ii) When AB = 15m
tan x = opposite side/ adjacent side
tan x = 8/15
x= arctan (8/15) [ inverse tan]
x= arctan(.53)
x =27.9
x=28°
