Question

I need help anybody ?

Answer 1

Answer and Step-by-step explanation:

Simply use the Pythagorean Theorem to solve.

The Pythagorean Theorem is used to solve for a side in right triangles.

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

Plug the sides values into the equation.

`A^(2) + 13^2 = 20^2\\\\A^2 + 169 = 400\\\\A^2 = 231\\\\A = 15.1987`<- This is the answer.
