Question

teorema de pitagoras:​

Answer 1

Resposta:

teorema diz que a²=b²+c²

a) a²=3²+9²

a²=9+81

a²=100

a=10

b) a²=5²+12²

a²=25+144

a²=169

a=13

c) a²=2²+6²

a²=4+36

a²=40

$a = \sqrt{40}$

$a = \sqrt{4 \times 10 }$

$a = \sqrt{2 {}^{2} } \times 10$

$a = 2 \sqrt{10}$

d)a²=9²+12²

a²= 81+144

a²=225

$a = \sqrt{225}$

$a = \sqrt{5 \times 25}$

$a = \sqrt{5 {}^{2} } \times 5$

$a = 5 \sqrt{5}$

e) a²= 7²+10²

a²= 49+100

a= 12,20 aproximadamente
