Answer:
Part 1) The third whole number is 44
Part 2) The third whole number is 40
Part 3) The third whole number is 25
Step-by-step explanation:
we know that
The Pythagoras theorem states that
In a right triangle
[tex]c^{2} =a^{2} +b^{2}[/tex]
where
c is the greater length side
a and b are the legs
Case 1) we have
33,55
step a
Let
[tex]a=33, b=55[/tex]
Find the value of c
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]c^{2} =33^{2} +55^{2}[/tex]
[tex]c^{2} =4,114[/tex]
[tex]c =64.14[/tex] ------> is not a whole number
step b
Let
[tex]a=33, c=55[/tex]
Find the value of b
[tex]b^{2} =c^{2} -a^{2}[/tex]
[tex]b^{2} =55^{2} -33^{2}[/tex]
[tex]b^{2} =1,936[/tex]
[tex]b=44[/tex]
Case 2) we have
42,58
step a
Let
[tex]a=42, b=58[/tex]
Find the value of c
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]c^{2} =42^{2} +58^{2}[/tex]
[tex]c^{2} =5,128[/tex]
[tex]c =71.61[/tex] ------> is not a whole number
step b
Let
[tex]a=42, c=58[/tex]
Find the value of b
[tex]b^{2} =c^{2} -a^{2}[/tex]
[tex]b^{2} =58^{2} -42^{2}[/tex]
[tex]b^{2} =1,600[/tex]
[tex]b=40[/tex]
Case 3) we have
60,65
step a
Let
[tex]a=60, b=65[/tex]
Find the value of c
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]c^{2} =60^{2} +65^{2}[/tex]
[tex]c^{2} =7,825[/tex]
[tex]c =88.46[/tex] ------> is not a whole number
step b
Let
[tex]a=60, c=65[/tex]
Find the value of b
[tex]b^{2} =c^{2} -a^{2}[/tex]
[tex]b^{2} =65^{2} -60^{2}[/tex]
[tex]b^{2} =625[/tex]
[tex]b=25[/tex]
