The height of the antenna on the roof of the local building is approximately 8 meters.
The situation forms a right angle triangle.
<h3>Properties of a right angle triangle:</h3>
- One of its angles is equals to 90 degrees
- The sides of the triangles can be calculated using Pythagoras theorem.
Therefore, let's find the height of the building and the radio antenna from the eye point.
Using trigonometric ratios,
tan 40° = opposite / adjacent
tan 40° = x / 25
where
x = the height of the building and the radio antenna from the eye point.
x = 25 tan 40
x = 25 × 0.83909963117
x = 20.9774907794 meters
Let's find the height of the building from his eye point.
tan 28° = y / 25
where
y = height of the building from his eye point
y = 25 × tan 28°
y = 25 × 0.53170943166
y = 13.2927357915 meters
Height of the antenna = 20.9774907794 - 13.2927357915 = 7.68475498786
Height of the antenna ≈ 8 meters

Answer:
0.28
Step-by-step explanation:
Refer the attached figure
Given :
People who live in their hometown and graduated from the college =8
People who do not live in their hometown and graduated from the college = 10
People who did not graduate from college and lives in home town = 6
People who did not graduate from college and do not live in home town = 4
To Find : Among people who do not live in their hometown, what is the relative frequency of not graduating from college?
Solution :
The total no. of people who do not live in home town whether they are graduated or not graduated = 14
People who did not graduate from college and do not live in home town = 4
Thus Among people who do not live in their hometown the relative frequency of not graduating from college :
People who did not graduate from college and do not live in home town/total no. of people who do not live in home town whether they are graduated or not graduated
⇒
⇒
⇒
Thus , Among people who do not live in their hometown the relative frequency of not graduating from college = 0.28
Answer:
18
Step-by-step explanation:
100% of 6 is 6 so 300% (which does not actually exist) would be 3 times as much. 6x3=18
