Is right triangle

Find out if the triangle ABC (with right angle at the vertex C) is right if:
a) a = 3dm, b = 40cm, c = 0.5m
b) a = 8dm, b = 1.2m, c = 6dm





a=3 dm b=40 cm dm=40/10  dm=4 dm c=0.5 m dm=0.5 10  dm=5 dm  d=a2+b2=32+42=5 dm d=c x=1
a1=8 dm b1=1.2 m dm=1.2 10  dm=12 dm c1=6 dm  e=a12+b12=82+122=4 13 dm14.4222 dm ec1  f=a12+c12=82+62=10 dm y=0
