(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
11 x minus 9 is equal to 90

3x−9=90
3 x minus 9 is equal to 90

11x−9=180

Answer 1

11x−9=180 and (7x−9)+4x=180 can be used to determine the measure of the two angles.
