Answer:
It is a right triangle
Explanation:
We are given the directions in which a bird flew to make a triangle.
We are required to determine whether the triangle is right angle.
What is a right triangle?
- It is a triangle that has a right angle between the shorter sides or legs
- The triangle also obeys the Pythagoras theorem, such that the square of the two legs is equal to the square of the hypotenuse.
- Such that if the two legs are, a and b while c is the hypotenuse.
Then, a² + b² = c²
In this case;
Taking the legs as a= 21 yards and b = 72 yards and the hypotenuse, c = 75 yards.
Then we can determine whether it is a right triangle;
a² = 21² = 441
b²= 72² = 5184
c² = 75² = 5625
a² + b² = 5625
Therefore; a² + b² = c²
Hence, the triangle is right triangle.
Dalton's Law of Partial Pressures, commonly applied to ideal gases, explains that the partial pressures of individual, non-reacting gases are equal to the total pressure exerted by the gas mixture. The given gas mixture composed of 90% argon and 10% carbon dioxide has the following partial pressures: 3.6 atm for argon and 0.4 atm for carbon dioxide (answer).
<em>Answer: The disasters are different according to their occurrence. For example, the causes of an earthquake cannot be the same as that of forest-fire. Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents etc.</em>
