Answer 1

• Teorema de pitágoras:

$b {}^{2} = h {}^{2} - a {}^{2} \\ b {}^{2} = 15 {}^{2} - 5 {}^{2} \\ b {}^{2} = 225 - 25 \\ b {}^{2} = 200 \\ b = \sqrt{200} \\ b = 10 \sqrt{2}$

• Resolvemos :

$l = \frac{15}{10 \sqrt{2} } + \frac{5}{10 \sqrt{2} } \\ \\ l = \frac{3 \sqrt{2} }{4} + \frac{5}{10 \sqrt{2} } \\ \\ l = \frac{3 \sqrt{2} }{4} + \frac{ \sqrt{2} }{4} \\ \\ l = \frac{3 \sqrt{2} + \sqrt{2} }{4} \\ \\ l = \frac{4 \sqrt{2} }{4} \\ \\ l = \sqrt{2}$

• L = raíz de 2
