Answer:
i only did the first one because you have missing numbers, but hopefully an example helps you
Step-by-step explanation:
Use the pythagorean theorem to find the length of the missing sides:
[tex]{a}^{2} + {b}^{2} = {c}^{2} [/tex]
1)
[tex] {9}^{2} + {9}^{2} = {c}^{2} [/tex]
[tex]81 + 81 = {c}^{2} [/tex]
[tex]162 = {c}^{2} [/tex]
[tex] \sqrt{162} = \sqrt{ {c}^{2} } [/tex]
[tex]12.73 = c[/tex]
