Using the pythagorean theorem, calculate the length of the missing sides (c1, c2, c3)​

the answer is 12

\begin{gathered} {13}^{2} = {5}^{2} + {b}^{2} \\ {b}^{2} = {13}^{2} - {5}^{2} \\ b {}^{2} = 169 - 25 = 144 \end{gathered}

=169−25=144

b = \sqrt{144} = 12b=

144

=12

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

vertical=18cm horizontal=18cm hypotenuse=25.5
