On a triangle, the vector from one vertex to another vertex is 〈-12,5〉. What is the length of the side?

Respuesta :

Answer:

13

Step-by-step explanation:

The magnitude of a vector < a, b > is

[tex]\sqrt{a^2+b^2}[/tex]

Given < - 12, 5 > then the length of the side is

[tex]\sqrt{(-12)^2+5^2}[/tex]

= [tex]\sqrt{144+25}[/tex]

= [tex]\sqrt{169}[/tex] = 13
