Which set of measures could represent the lengths of the sides of a right triangle

Pythagorean triple

Step-by-step explanation:

The sides of a right triangle can be specifically referred to as a Pythagorean triple.

This is because, the sum of the square of the longest of these three lengths as any point in time is equal to the summation of the squares of the other two lengths.

The longest of these lengths can be referred to as the hypotenuse, with its square being equal to the sum of the squares of the other two sides.

The law guiding the operations of the Pythagorean triple is referred to as the Pythagoras’ theorem and it is a theorem which is exclusive to finding the lengths of the sides of a right triangle of two of the sides are known and the other third side is missing

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
