Question

me podrian ayudar porfavor

Answer 1

Respuesta:

${3}^{2} + {5}^{2} = {c}^{2} \\ 9 + 25 = {c}^{2} \\ 34 = {c}^{2} \\ \sqrt{34} = c \\ 5.83 = c$

${x}^{2} + {2}^{2} = {5}^{2} \\ {2}^{2} - {5}^{2} = - {x}^{2} \\ 4 - 25 = - {x}^{2} \\ - 21 = - {x}^{2} \\ {x}^{2} = 21 \\ x = \sqrt{21} \\ x = 4.58$
