Question

alguien me ayuda porta? :(​

Answer 1

PROBLEMA 7

${k}^{2} + {7}^{2} = {25}^{2} \\ {k}^{2} + 49 = 625 \\ {k}^{2} = 625 - 49 \\ {k}^{2} = 576 \\ k = \sqrt{576} \\ k = 24$

PROBLEMA 8

${m}^{2} + {12}^{2} = {13}^{2} \\ {m}^{2} + 144 = 169 \\ {m}^{2} = 169 - 144 \\ {m}^{2} = 25 \\ m = \sqrt{25} \\ m = 5$

PROBLEMA 9

${r}^{2} + {4}^{2} = (4 \sqrt{3} ) {}^{2} \\ {r}^{2} + 16 = 48 \\ {r}^{2} = 48 - 16 \\ {r}^{2} = 32 \\ r = \sqrt{32} \\ r = 4 \sqrt{2}$

PROBLEMA 10

${x}^{2} + {16}^{2} = {20}^{2} \\ {x}^{2} + 256 = 400 \\ {x}^{2} = 400 - 256 \\ {x}^{2} = 144 \\ x = \sqrt{144} \\ x = 12$
