Question

Cunoscind catetele ,aflati ipotenuza :
a)3cm si 4 cm
b)6cm si 8 cm
c)5cm si 12 cm
d)3dm si 7 dm
e) 2 cm si 20 mm
f)radical din 2 cm si radical din 3 cm

Answer 1

a) ipotenuza=√(3²+4²)=√(9+16)=√25=5 cm
b) ipotenuza=√(6²+8²)=√(36+64)=√100=10 cm
c) ipotenuza=√(5²+12²)=√(25+144)=√169=13 cm
d) ipotenuza=√(3²+7²)=√(9+49)=√54=3√6 cm
e) ipotenuza=√(2²+20²)=√(4+400)=√404=2√101 cm
e) ipotenuza=√[(√2)²+(√3)²]=√(2+3)=√5 cm
