Answer: 14 students will be in each group
84 divided by 6 = 14
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:
In the given expression x:6 :: 3:9 , x = 2
Step-by-step explanation:
Here, the given expression is:
x:6 :: 3:9
or, x : 6 = 3 :9
So, by the RATIO OF PROPORTIONALITY:

or, x = 2
Hence, in the given expression x:6 :: 3:9 , x = 2
8.64 - 3.15 = $5.49 if this is what you are asking
you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B
