Which best explains whether a triangle with side links 5 cm 13 cm and 12 cm is a right triangle

Genrish500 [490]

Answer:

$5^{2} + 12^{2} = 13^{2}\\25+144=169$

Step-by-step explanation:

Squaring base and adjacent then adding them and finally getting the squareroot of the sum gives hypotenuse of a right angle triangle. In this case, squaring 5 and 12 then getting their square roots gives you 13, proving that it is a right angle

Here is the proof

$5^{2}=25\\12^{2}=144\\13^{2}=169\\25+144=169$

Therefore, the above dimensions are for a right angled triangle.

Answer:

The answer is 3 , 1 , 2 .

Step-by-step explanation:

I will give an example.

e.g.

x² + 3x + 2

Step 3 :

Set the equation equal to zero :

x² + 3x + 2 = 0

Step 1 :

Completely factor the equation :

x² + x + 2x + 2 = 0

x(x+1) + 2(x+1) = 0

(x+2)(x+1) = 0

Step 2 :

Set each factor equal zero and then solve for the variable :

(x+2)(x+1) = 0

x + 2 = 0

x = -2

x + 1 = 0

x = -1
