Sum of angles in a triangle = 180º
Solve x:
2x + (3x - 20) + 4x = 180
2x + 3x - 20 + 4x = 180
9x - 20 = 180
9x = 200
x = 22.2º
Answer : x = 22.2.
------------------------------------------------------------------------------------------
Additional Information:
Find the angles:
2x = 2 (22.2) = 44.4º
3x - 20 = 3(22.2) - 20 = 46.6º
4x = 4(22.2) = 88.8º

oh yah its not given to find
I am requesting you that i answer but u didn't respond
Thanks too free..
I was editing the answer. That is why I was not responding.
Edited to include the angles, as you request.

2x+3x-20+4x= 180 degrees
9x=180+20
9x = 200
x= 200/9
=22.2 degrees
then the angles are 44.4, 46.6, 88.8
hope this is useful to you
