Answer 1

Cazul 1:
b=3 cm
c=4 cm
a^2=b^2+c^2
a^2=9+16
a^2=25
a=5 cm

Cazul 2:
b=6 dm
c=0.8 m=8 dm
a^2=b^2+c^2
a^2=36+64
a^2=100
a^2=10 dm

Cazul 3:
b=√6 cm
c=√2cm
a^2=b^2+c^2
a^2=6+2
a^2=8
a=2√2 cm

Cazul 4:
a=15 cm
c=12 cm
b^2=a^2-c^2
b^2=225-144
b^2=81
b=9 cm

Cazul 5:
a=12 dm
b=60cm=6 dm
c^2=a^2-b^2
c^2=144-36
c^2=108
c=6√3 dm

Cazul 6:
a=24√2 cm
c=24 cm
b^2=a^2-c^2
b^2=1152-576
b^2=576
b^2=24 cm
