hi, sweet frns here is ur answer.
in the figure AOB is a line
so, sum of all the angle will be 180
so,3x-5+55+x+20=180
or 4x+70=180
or4x=180-70
or4x=110
or x=110/4
x=27.5

As we know,
So,
( 3x - 5 ) + ( 55 ) + ( x + 20 ) = 180°
3x - 5 + 55 + x + 20 = 180°
3x + x + 55 + 20 - 5 = 180°
4x + 75 - 5 = 180°
4x + 70 = 180°
4x = 180° - 70
4x = 110°
x = 110° / 4
x = 27.5°
( 3x - 5 ) + 55 + ( x + 20 ) = 180°
3(27.5) - 5 + 55 + 27.5 + 20 = 180°
82.5 + 27.5 + 55 + 20 - 5 = 180°
110 + 75 - 5 = 180°
180° = 180°
Ask if any doubt :)
