Question

Preciso do cálculos

Answer 1

a)
${x}^{2} = {5}^{2} + {12}^{2} \\ {x}^{2} = 25 + 144 = \\ {x}^{2} = 169 \\ x = \sqrt{169 } = 13$
b)
${x}^{2} = {3}^{2} + {2}^{2} \\ {x}^{2} = 9 + 4 \\ {x}^{2} = 13 \\ x = \sqrt{13}$
c)
${x}^{2} = ( 2 { \sqrt{2} }^{2} ) + { \sqrt{10} }^{2} \\ {x}^{2} = 8 + 10 \\ {x}^{2} = 18 \\ x = \sqrt{18}$
d)
${6}^{2} = 2 {x}^{2} \\ 36 = 2 {x}^{2} \\ 36 \div 2 = {x}^{2} \\ 18 = {x }^{2} \\ x = \sqrt{18}$
