Question

determinati Lungimea ipotenuzei unui triunghi dreptunghic ale carui catete au lungimile de:
a)3 si 4
b)6 si 8
c)15 si 20
d)10 si 10√3
e)5√3 si 5√2
f)2√2 si 2√7
g)24 si 18

Answer 1

Ip=ipotenuza
a)Ip=√(3²+4²)=√(9+16)=√25=5
b)Ip=√(6²+8²)=√(36+64)=√100=10
c)Ip=√(15²+20²)=√(225+400)=√625=25
d)Ip=√[10²+(10√3)²]=√(100+300)=√400=20
e)Ip=√[(5√3)²+(5√2)²]=√(75+50)=√125=5√5
f)Ip=√[(2√2)²+(2√7)²]=√(8+28)=√36=6
g)Ip=√(24²+18²)=√(576+324)=√900=30
