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

the triangle is a right triangle because 52 + 122 = 132.
the triangle is not a right triangle because 5 + 13 > 12.
the triangle is not a right triangle because 52 + 132 > 122.
the triangle is not a right triangle because 5 + 12 > 13.

This triangle is, in fact, a right triangle, though the numbers you have for answers don't match up. With the theorem a^2 + b^2 = c^2, the longest side is the hypotenuse and c^2. Substituting and simplifying gives you 25 (5^2) + 144 (12^2) = 169 (13^2). 25 + 144 is equal to 169, which proves it.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
