The point of observation is 2500 m away from the foot of the building.
The angle of elevation is 4°.
We need to find the height 'h' of the building.
With respect to 4°,
2500 is the adjacent side.
'h' is the opposite side.
The trigonometric ratio associating opposite & adjacent is tan.
We have


Cross multiplying we get
h = 2500 tan4°
h= 174.82 m
Option B) is the right answer.
Answer:
40 teabags for 0.96 (this is the most british question I've ever saw)
Step-by-step explanation:
1.62 / 60 = 0.027 (price per teabag)
0.96 / 40= 0.024 (price per teabag)
40 teabags for 0.96 is the better deal
