hola Marie estas son las respuestas amiga
1
[tex]c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
[tex]c = \sqrt{ {10}^{2} + {8}^{2} } \\ c = \sqrt{100 + 64} \\ c = \sqrt{164} \\ c = 2 \sqrt{41} [/tex]
2.
[tex]b = \sqrt{c {}^{2} } - {a}^{2} [/tex]
[tex]b = \sqrt{ {12}^{2} - {10 }^{2} } \\ b = \sqrt{144 - 100} \\ b = \sqrt{44} \\ b = 2 \sqrt{11} [/tex]
3.
[tex]c = \sqrt{ {9}^{2} + {8}^{2} } \\ c = \sqrt{81 + 64} \\ c = \sqrt{145} [/tex]
4.
[tex]b = \sqrt{15 {}^{2} - 12 {}^{2} } \\ b = \sqrt{225 - 144} \\ b = \sqrt{81} \\ b = 9[/tex]
esas son las respuestas espero te sirva para el examen amiga
