Ramiro Fleming · Answer 1

The interior angles of a triangle always adds up to 180 degrees. So add the equations together and set it equal to 180. (2x+3+4x+2+2x-1=180) Solve and you get X=22. Plug that back into the equations. You should get A=47, B=43, and C=90. To check this answer add A+B+C together and you get 180 degrees.
