Question

GOOD AT MATH!! PLEASE HELPPP

Answer 1

B. 5

Explanation:

Use the pythagorean theorem to solve:
`a^(2)`+
`b^(2)`=
`c^(2)`.

`a^(2)`+
`12^(2)`=
`13^(2)`

`a^(2)`+144=169

Subtract 144 from 169.

`a^(2)`-144=169-144

`a^(2)`=25

Square root to get a.

`√(a)`=
`√(25)`

a= 5

Answer 2

Square root of 13^2 - 12^2 = 5
