Question

por favor ayudame lo necesito para hoy​

Answer 1

Explicación paso a paso:

1)

${x}^{2} = {5}^{2} + {12}^{2} \\ {x }^{2} = 25 + 144 \\ {x}^{2} = 169 \\ x = \sqrt{169} \\ x = 13$

2)

${x}^{2} = {4}^{2} + {2.5}^{2} \\ {x}^{2} = 16 + 6.25 \\ {x}^{2} = 22.25 \\ x = \sqrt{22.25} \\ x = 4.71 \: m$

3)

${a}^{2} + {3}^{2} = {5}^{2} \\ {a}^{2} + 9 = 25 \\ {a}^{2} = 16 \\ a = \sqrt{16} \\ a = 4 \: m$
