Question 1036227
That information only means that  90+2y=7y+9, because two vertical angles are congruent.  Solve for y.  The value of y IS NOT 122.4.  But knowing the expression of either angle, USE y to find either angle.  Is this 122.4?


{{{90+2y=7y+9}}}
{{{90=5y+9}}}
{{{81=5y}}}
{{{y=81/5}}}


{{{7(81/5)+9=theAngle}}}
