The missing side of ABC = 13
The missing side of FDE = 24

Pythagorean Theorem: a² + b² = c²

Pythagorean Theorem is for right-angled triangle only.

The missing side of ABC is:
12² + 5² = AC²

169 = AC²

AC = √169

AC = 13

The missing side of FDE is:
DE² + 10² = 26²

DE² = 26² - 10²

DE² = 576

DE = √576

DE = 24
