Question

What is the length of the unlabeled leg of the triangle?

Answer 1

Answer: It is 5

Explanation:

`A^(2)` +
`B^(2)`=
`C^(2)`

In this case A^2 is what we don't know.

B is 12 and C is 13.

The equation would now be ?+
`12^(2)`=
`13^(2)`

`12^(2)`=144

`13^(2)`= 169

so the equation is now, ?+144=169 so if you subtract, 144 from 169 to find out what "?" is, it will be 25

so if you square root
`√(25)` , it will be 5 (hence
`5^(2)` being 25)
