Answer:
The perimeter of the triangle is 30 units.
Step-by-step explanation:
So
[tex]x^2[/tex]= [tex]5^2\\[/tex]+[tex]12^2[/tex]
[tex]x^2[/tex]= 25+144
[tex]x^2[/tex]=169
[tex]x^2\\[/tex]=[tex]\sqrt 169[/tex]
[tex]x[/tex]=13
The greatest side / hypotenuse of the triangle = 13
The perimeter of a triangle = Sum of all sides
5+12+13
30 units
