Question

nos triângulos retângulos abaixo calcule os elementos desconhecidos​

Answer 1

a)

$25h = 20.15 \\ h = \frac{20.15}{25} \\ h = \frac{5.4.5.3}{5.5} = 12$

b)

${a}^{2} = {6}^{2} + {8}^{2} \\ a = \sqrt{36 + 64} \\ a = \sqrt{100} \\ a = 10$

c)

${h}^{2} = 16.9 \\ h = \sqrt{16.9} \\ h = 4.3 \\ h = 12$

d)

${3}^{2} = 5n \\ n = \frac{9}{5}$

${4}^{2} = 5m \\ m = \frac{16}{5}$

e)

${h}^{2} = 5.15 \\ h = \sqrt{5.5.3} = 5 \sqrt{3}$

$20.5 \sqrt{3} = 10b \\ b = \frac{100 \sqrt{3} }{10} \\ b = 10 \sqrt{3}$

${c}^{2} = 20.5 \\ c = \sqrt{100} \\ c = 10$
