Question 931641

given JKMN is a rectangle; so all angles are {{{90}}} degrees

if m < {{{NKM= x^2+4}}}=>{{{ x^2+4=90}}}..solve for {{{x}}}

{{{ x^2=90-4}}}

{{{ x^2=86}}}

{{{ x=sqrt(86)}}}

{{{ x=9.273618495495704}}} exact solution (and, we will not need negative solution)

{{{ x=9.27}}} approximate solution

and

m < {{{NKJ= x+30}}} => m < {{{x+30= 90}}}=> m < {{{x=60}}}
