Which two equations can be used to determine the measure of these two angles? (1 point) Responses (7x−9)−4x=90 open paren 7 x minus 9 close paren minus 4 x is equal to 90 (7x−9)+4x=180 open paren 7 x minus 9 close paren plus 4 x is equal to 180 (7x−9)+4x=90 open paren 7 x minus 9 close paren plus 4 x is equal to 90 11x−9=90

The two equations that can be used to determine the measure of the two angles are:

1) (7x−9)−4x=90
2) 11x−9=90
