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,

$\bf \: Sum \: of \: linear \: pairs \: is \: equal \\ \bf \: to \: 180$

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°

$\bf \: You \: can \: have \: a \: check...$

( 3x - 5 ) + 55 + ( x + 20 ) = 180°

$\bf \: Putting \: the \: value \: of \: x.$

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 :)
