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

Mid point b/w (18,-6),(0,0)
X = 0+18/2 = 9
y = 0-6/2 = -3
thus mid point is (9,-3)
Answer:
The answer is x=4 and y=−2
Answer:
<em>The amount of rabbit after 1 year will be </em><em>320</em><em>.</em>
Step-by-step explanation:
A gardener brought 5 rabbits, after 2 months rabbits became 10.
The growth continues on the same ratio.
This represents a geometric sequence with 1st term as 5 and common ratio as 2.
As we have to find the amount of rabbit after 1 year, so the we have to find 
th term. As the time difference between each counting is 2 months, so we divided 1 year or 12 months of time by 2.
nth term in a G.P is,
Putting the values,
