Let AB = t. And since X lies in the middle, so AX=BX = t/2 .
Let the height of the smaller flagpole is AO and of larger flagpole is BP .
Using tangent ratio rule in each triangle, we will get

Answer:
The ballonist is at a height of 3579.91 ft above the ground at 3:30pm.
Step-by-step explanation:
Let's call:
h the height of the ballonist above the ground,
a the distance between the two observers,
the horizontal distance between the first observer and the ballonist
the horizontal distance between the second observer and the ballonist
and
the angles of elevation meassured by each observer
S the area of the triangle formed with the observers and the ballonist
So, the area of a triangle is the length of its base times its height.
(equation 1)
but we can divide the triangle in two right triangles using the height line. So the total area will be equal to the addition of each individual area.
(equation 2)
But we can write in terms of
, like this:
And for will be the same:
Replacing in the equation 2:
And replacing in the equation 1:
So, we can replace all the known data in the last equation:
Then, the ballonist is at a height of 3579.91 ft above the ground at 3:30pm.
Answer:
Answer is 135 plant
Step-by-step explanation:
We have given that,
In 5 min Renee can plant 15 plant.
That means in one minute Renee can plant plant.
i.e. Rate of planting = 3 plant per minute
So, In 45 minutes , she can plant 45×3 plant
i.e Plant she can plant in 45 minute = 135 plant
