Question 1151798
the angle measures of △ {{{GHI}}} in order from smallest to largest, 

given that" 

{{{HI=42}}} miles,=> shortest side is opposite the smallest angle which is < {{{I}}}
{{{GH=69}}} miles, =>is opposite the angle < {{{G}}}
{{{GI=82}}} miles => longest side  is opposite the largest angle which is < {{{H}}}


{{{G=cos^-1(b^2+c^2-a^2)/(2bc)=cos^-1(42^2+82^2-69^2)/(2*42*82)=57.24}}}°
{{{I=cos^-1(a^2+c^2-b^2)/(2*a*c)=cos^-1(69^2+82^2-42^2)/(2*69*82)=30.79}}}°
{{{H=cos^-1(a^2+b^2-c^2)/(2*a*b)=cos^-1(69^2+42^2-82^2)/(2*69*42)=91.97}}}°
