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.
1. Definition Of Isotope:
Two or more forms of the same element contain equal amounts of protons but different amounts of neutrons.
2. What Does The Number Next To Isotopes Signify?
Atomic mass is the number next to the isotope.
3. How Can You Tell Isotopes Apart?
To tell the difference, isotopes will have different atomic mass than other atoms that make the same element.
