Question 132111
{{{a^2+b^2=c^2}}} Start with Pythagorean's Theorem



{{{a^2+2^2=(sqrt(29))^2}}} Plug in {{{b=2}}} and {{{c=sqrt(29)}}}



{{{a^2+4=29}}} Square 2 to get 4. Square {{{sqrt(29)}}} to get 29


{{{a^2=25}}} Subtract 4 from both sides


{{{a=sqrt(25)}}} Take the square root of both sides



{{{a=5}}} Simplify

Answer:


So the length of the missing side is {{{a=5}}}
