Answer:
n = 9
Step-by-step explanation:
3(n+7)=48
distribute
3n +21 = 48
subtract 21 from each side
3n = 48-21
3n = 27
divide by 3
3n/3 = 27/3
n = 9
There are two sides (heads and tails). So one head would be 1/2, and one tail would also be 1/2.
Answer:

Step-by-step explanation:
Given that,
The height of the tower, h = 40 m
The angle of elevation is 30°
We need to find the distance between the tower and the point. Let the distance is x. Using trigonometry,

So, the distance between the tower and the point is equal to
.
Let, the number = n
It would be: 2n = 28
n = 28/2
n = 14
In short, Your Answer would be 14
Hope this helps!
