Answer 1

$\large\displaystyle \mathsf{x^2=12^2+9^2 }$

$\large\displaystyle \mathsf{ x^2=144+81}$

$\large\displaystyle \mathsf{x^2=225 }$

$\large\displaystyle\text{ \mathsf{ x=\sqrt{225}} }$

$\large\displaystyle\text{ \boxed{\boxed{ \mathsf{x=15}} } }$

$\large\displaystyle \mathsf{ y^2+8^2=17^2}$

$\large\displaystyle \mathsf{y^2+64=289 }$

$\large\displaystyle \mathsf{ y^2=289-64}$

$\large\displaystyle \mathsf{ y^2=225}$

$\large\displaystyle\text{ \mathsf{y=\sqrt{225} } }$

$\large\displaystyle\text{ \boxed{\boxed{\mathsf{y=15 }}} }$
