Step-by-step explanation:
Answer:
B) { 51, 149, 140 }
C) { 16, 63, 65 }
Step-by-step explanation:
We need to choose Pythagoras theorem formula

now, we can verify each options
option-A:
a=1
b=1
c=1
now, we can verify formula


We can see that left side is not equal to right side
so, this is FALSE
option-B
a=51
b=140
c=149
now, we can verify formula


We can see that left side is equal to right side
so, this is TRUE
option-C
a=16
b=63
c=65
now, we can verify formula


We can see that left side is equal to right side
so, this is TRUE
option-D:
a=6
b=8
c=11
now, we can verify formula


We can see that left side is not equal to right side
so, this is FALSE
