Question

achar o valor do Y e do x

Answer 1

${y}^{2} = {10}^{2} - {6}^{2} \\ {y}^{2} = 100 - 36 = 64 \\ y = 8$

então:

${12}^{2} + {9}^{2} = {x}^{2} \\ {x}^{2} = 144 + 81 = 225 \\ x = 15$

Answer 2

Resposta:

${x}^{2} = {x}^{2} + {x}^{2} \\ {10}^{2} = {y}^{2} + {6}^{2} \\ 100 = {y}^{2} +36 \\ {y }^{2} =100 - 36 \\ {y}^{2} = 64 \\ y = 8$

${x}^{2} = {x}^{2} + {x}^{2} \\ {x}^{2} = {12}^{2} + {9}^{2} \\ {x}^{2} = 144 + 81 \\ {x}^{2} = 225 \\ x = 15$
