Answer:

30,40,50

Step-by-step explanation:

If it is a right triangle then the pythagorean theorum would work

a^2+b^2=c^2

30^2+40^2=50^2

900+1600=2500

2500=2500

this means that 30,40,50 is the right answer

*******extra********

also 30,40,50 is a pythagorean triplet

pythagorean triplets form right angles

this one came from the original triplet of 3,4,5---just multiply by 10
