Answer:
in year 7
Step-by-step explanation:





So in year 7, the animal would be placed on the endangered species list.
The balloon is 1366 meters above the ground.
Step-by-step explanation:
Step 1:
The angle of depression from the balloon is 41° and the distance from the balloon to the meteorologist on the diagonal is 1,810 meters.
So a right-angled triangle can be formed using these measurements. The angle of the triangle is 41° while the adjacent side of the triangle measures x meters and the hypotenuse side of the triangle measures 1,810 meters.
We need to find the adjacent side's length of the triangle.
Step 2:
Since we have the length of the hypotenuse and need to calculate the length of the adjacent side we use the cos of the given angle.
The adjacent side of the triangle = x meters.
The hypotenuse of the triangle = 1,810 meters.


So the balloon is 1,366.007 meters above from the ground. Rounding this off to the nearest meter it is 1,366 meters from the ground.
Step-by-step explanation:
This is called the binomial square. It is stated as: the square of the difference of two binomials (two unlike terms) is the square of the first term plus the second term minus twice the product of the first and the second term.
