Question

esta pregunta es para ya es de geometria​ si no que en los nombres de las materias no me aparece me toco colocar otra cosa para poder dejar la pregunta

Answer 1

A: 25

${x}^{2} = {15}^{2} + {20}^{2} \\ {x}^{2} = 225 + 625 \\ {x}^{2} = 625 \\ x = \sqrt{625} \\ x = 25.$

B: 8

${17}^{2} = {15}^{2} + { \alpha }^{2} \\ 289 = 225 + { \alpha }^{2} \\ 289 - 225 = { \alpha }^{2} \\ 64 = { \alpha }^{2} \\ \sqrt{64} = \alpha \\ \alpha = 8$

C: 23.32

${x}^{2} = {12}^{2} + {20}^{2} \\ {x}^{2} = 144 + 400 \\ {x}^{2} = 544 \\ x = \sqrt{544} \\ x = 4 \sqrt{34} = 23.32$

D: 41

${y}^{2} = {9}^{2} + {40}^{2} \\ {y}^{2} = 81 + 1600 \\ {y}^{2} = 1681 \\ y = \sqrt{1681} \\ y = 41$
