Answer:
Yes, the set of numbers create a Pythagorean triple
Explanation:
we know that
If a set of numbers create a Pythagorean triple, then the set of numbers must satisfy the Pythagorean Theorem
![c^2=a^2+b^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/byhrr90olo1xo4n215kg0bc367cjwlvx2c.png)
where
c is the greater side
a and b are the legs (perpendicular sides)
we have
![c=7.5\\a=2.1\\b=7.2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/4chr5b8w7a1vwszmsbc1ubolyr0mwib6pg.png)
substitute
![7.5^2=2.1^2+7.2^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/dv90x7ryj09zrlf0moxgg8zbf7l9z77t85.png)
![56.25=4.41+51.84](https://img.qammunity.org/2021/formulas/mathematics/middle-school/tkg35q66rxkgkbjcr34yeruecp26editan.png)
----> is true
therefore
Yes, the set of numbers create a Pythagorean triple
