Question

Determine os valores de x, y, w e z.​

Answer 1

$(x) {}^{2} = (8 \times 2) {}^{2} + (15 \times 2) {}^{2} \\ x { }^{2} = 8 {}^{2} \times 2 {}^{2} + 15 {}^{2} \times 2 {}^{2} \\ x {}^{2} = (8 {}^{2} + 15 {}^{2} ) \times 2 {}^{2} \\ x {}^{2} = 289 \times 4 \\ x {}^{2} = 1156 \\ x = \sqrt{1156} \\ x = 34$
