Answer 1

Answer:

2.

Step-by-step explanation:

$a^{2} +b^{2} =c^{2}\\5^{2} +12^{2} =13^{2} \\25+144=169\\169=169$

Answer 2

Answer:5,12,13

Step-by-step explanation: first you write out

a^2 or a squares + b^2=C ^2 You plug in for a and b the smaller numbers then for c you put the biggest number. Now square everything. And you should get 25 for a. 144 for b. 169 for c. Now add a and b which is25+144 and that equals 169. So 5,12,13 is your answer.
