Step-by-step explanation:
Answer:
61.15 m
Step-by-step explanation:
From trigonometry :
Tan x = opposite / Adjacent
x = 28°
Tan 28 = distance from base to fire / height
0.5317094 = distance from base to fire / 115
distance from base to fire = 115 * 0.5317094
distance from base to fire = 61.15 m
Just divide 48 by 8 to give 6.
The solution set is answer A.
A20-a18=a1+19d-a1-17d=2d =281-97
so
d=92
