Answer:
Step-by-step explanation:
Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get

⇒
⇒
⇒
⇒
Thus, the length of altitude is: 12 cm.
Now, 
⇒
⇒
Also, 
⇒
⇒
Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.
Step-by-step explanation:
- 3over4 which is 75percent
From the graph, we can actually see that as the altitude increase, the
value of the pressure decreases. Or if we say it the opposite way, as the
altitude decreases (approaches sea level), the pressure increases, therefore
the answer is:
As the altitude approaches sea level, the atmospheric
pressure increases.
Answer:
The constant term is 6
The x³ term has a coeficient of 12
The resulting polynomial has degree 4
