Answer: A

5,12,13 is a common Pythagorean triple, the second on the list after 3,4,5

B and C aren't on the list, and they would be if they were Pythagorean Triples, which is a list of natural number length sides (a,b,c) which satisfy the Pythagorean Theorem, a²+b²=c², making them the sides of a right triangle.

Let's verify:

5²+12² = 25+144 = 169 = 13² √

4²+4² = 16+16 = 32 ≠ 8² √

2²+3² = 4+9 = 13 ≠ 4² √

How to solve for x and y

Minchanka [31]

Answer-

The values of x and y are 20° and 30, respectively.

Solution-

As in the given triangle all the angles are same so it must a equilateral triangle.

In an equilateral triangle all the measurements of the angles and side length are same. The measurement of the angels are 60°.

As given in the question one side length is 46, so all the side length are same.

So,

$\Rightarrow y+16=46\\\\\Rightarrow y=46-16\\\\\Rightarrow y=30$

We know that an exterior angle of a triangle is equal to the sum of the opposite interior angles. 80° is the exterior angle opposite to x and one angle of triangle at the top vertex.

$\Rightarrow 80^{\circ}=x+60^{\circ}$

$\Rightarrow x=80^{\circ}-60^{\circ}$

$\Rightarrow x=20^{\circ}$

Therefore, the values of x and y are 20° and 30, respectively.

Which set of three numbers could represent the lengths of the sides of a right triangle?

Lubov Fominskaja [6]

Answer=5,12,13

Just plug all of these values into the pythagorean theorem. If they work, then they could represent a right triangle.

For example:
5²+12²=13²
25+144=169
169=169
