HELP PLEASEEE

Part A: yes

Part B: yes

Part C: yes

Step-by-step explanation:

Part A:

77² + 420² = 427²

5,929 + 176,400 = 182,329

182,329 = 182,329

Part B:

279² + 440² = 521²

77,841 + 193,600 = 271,441

271,441 = 271,441

Part C:

39² + 760² = 761²

1,521 + 577,600 = 579,121

579121 = 579,121
