Question

I need help plzzz...thanks

Answer 1

x=10.58

Explanation:

To find the side length of a right triangle, you can use the Pythagorean theorem.

The Pythagorean theorem is
`a^2+b^2=c^2`

the c is the hypotenuse of the triangle, so 16.

the a and b are the other sides of the triangle, so x and 12.

Therefore,
`x^2+12^2=16^2`

now you can solve the equation.

`x^2+144=256`

-144 -144

`x^2=112`

now you have to square root both sides of the equation.

`√(x^2) =√(112)`

x=10.58

Answer 2

a^2+12^2=16^2

then just solve for a
