Me urgeeeeeeeeeeeeeeeeeeeeeeeee

Respuesta:
[tex] {x}^{2} = {18}^{2} - {10}^{2} [/tex]
[tex] {x}^{2} = 324 - 100[/tex]
[tex] {x}^{2} = 224[/tex]
[tex]x = \sqrt{224} [/tex]
[tex]x = 14.97[/tex]
Explicación paso a paso:
el lado faltante se llamara : " x "
18² = x² + 10²
324 = x² + 100
324 - 100 = x²
224 = x²
√224 = x
14,97 cm. = x
