Question

calcule os valores de x e y na figura a baixo

Answer 1

${10}^{2} = {6}^{2} + {y}^{2} \\ {y}^{2} = 100 - 36 \\ {y}^{2} = 64 \\ y = \sqrt{64} \\ y = 8m$
${x}^{2} = {9}^{2} + {(y + 4)}^{2} \\{x}^{2} = {9}^{2} + {(8 + 4)}^{2} = {9}^{2} + {12}^{2} \\ {x}^{2} = 81 + 144 \\ {x}^{2} = 225 \\ x = \sqrt{225} \\ x = 15m$
