A is the answer I think

Answer:

30,40,50

Step-by-step explanation:

We use the Pythagorean theorem to find out if they would be sides of a right triangle

the Pythagorean theorem states that the two shorter sides squared added together equal the longest side square

for 30, 40 , 50

[tex]30^2=900\\40^2=1600\\1600+900=2500\\50^2=2500\\2500=2500[/tex]

2500=2500 therefore that is the correct answer
