Question 1002734
if the diagonal (hypotenuse) of a large right triangle is {{{c=6mi}}} long,and if one leg is {{{a=2mi}}}, use Pythagorean theorem to find out how long is the other leg {{{b}}}

{{{c^2=a^2+b^2}}}

{{{b^2=c^2-a^2}}}

{{{b^2=(6mi)^2-(2mi)^2}}}

{{{b^2=36mi^2-4mi^2}}}

{{{b^2=32mi^2}}}

{{{b=sqrt(32mi^2)}}}

{{{b=sqrt(2*16)mi}}}

{{{b=4*sqrt(2)mi}}}...exact length of the other leg

{{{b=4*1.414213562373095mi}}}

{{{b=5.65685424949238mi}}}

{{{b=5.7mi}}}........approximately
