pls help! will give brainlist!

Answer:
Yes
Step-by-step explanation:
It will be a right-angle triangle if it satisfies the pythagoras theorem
12.5² = 156.25
10² = 100
7.5² = 56.25
Since 12.5² = 10² + 7.5²,
it is a right-angle triangle with 90° at C (because it's opposite the longest side, the hypotenuse)
