Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?

5-12-13 is a Pythagorean Triple.

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

We can use the Pythagorean Theorem to prove that 5-12-13 is a right triangle:

5² + 12² = 13²

25 + 144 = 169

169 does equal 169.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
