Question 1193078
I guess you have a parallelogram. If so than {{{m∠A =m∠C}}} and {{{m∠B =m∠D}}}


given:

{{{m}}} ∠ {{{A = (2x + 4)}}}°
and
{{{m}}} ∠ {{{B = (3x -34)}}}°.


then

{{{m }}}∠ {{{A = 180}}}- {{{m}}} ∠ {{{B }}}

{{{2x + 4=180-(3x -34)}}}

{{{5x = 210 }}}

{{{x=42}}}


then

{{{m}}}∠{{{A = (2*42 + 4) =88}}}°=>{{{m}}}∠{{{C=88}}}°

{{{m}}}∠{{{B = (3*42 -34)=92}}}°=>{{{m}}}∠{{{D=92}}}°
